[Rails] More than one submit_tag in a single form

[Indu RS]

Hai everyone ,
I have a list of users(each user in a row)and an Approve button for each
user. I wish to change the status of the user to be approved when I
click on the Approve button of a user. When I tried getting all the
users in the params hash. I want to get the id of the user according to
which "Approve" button I clicked. How can I implement this one?
Thanks in advance.

Couldn't find Stream without an ID problem

i have  tried to enter data in new.html.erb file like:

[Rails] Re: Error in Mysql Connection

[Freddy Andersen]

I'm guessing in you database.yml file you have this:
development:
  adapter: mysql

So you need todo this:

# gem install mysql or if mysql is in a none standard area you need to
point to mysql_config like this:
# gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/
mysql_config (or where ever you have mysql installed)

Show us output from the following:

gem list
inside of you application => rake gems

[Rails] Upload File Using Form

[Jason Hhh]

I am trying to upload a CSV file through a form, process it, then input
the values in the file it into my database.  So first step, I need to
upload the file.  I created the form, uploaded a test file but I am
having trouble accessing the file in my controller.  I can access a hash
but all contains is the original filename of the file.  I guess my
question is how can I access this file and save it so that I can later
pass it to a CSV processing function.  I assume the file is uploaded to
some sort of temp file?  I am new at rails but I have accomplished
uploading and saving files in PHP before.  Any help would be great.

Thanks,

Jason

[Rails] Re: Error in Mysql Connection

[RichardOnRails]

I looked at you question again, which led me to add a couple of more
things:

Did you notice the advice:
"!!! The bundled mysql.rb driver has been removed from Rails 2.2.
Please
install the mysql gem and try again"

If you don't know how to use the "gem" system,  just Google for gem.
But if you use SQLite3,  you won't have to deal with installing MySQL.

Furthermore,  you must have found a way to opt for WEBrick.  The norm
for Rails 2 is Mongrel as the webserver.  Again, I recommend you go
with the default.

HTH,
Richard

[Rails] Re: Error in Mysql Connection

[RichardOnRails]

With Rails 2,  the default database server is SQLite3.  You apparently
added the optional MySQL.  I recommend you "go with the flow", i.e.
restart and allow the default DBMS to be used.

[Rails] .erb invoked unexpectedly

[RichardOnRails]

I've got an app that starts up with:
map.root :controller => "csvs", :action => 'startup'

The csvs_controller.rb is posted on http://www.pastie.org/340100

The startup routine checks the RAILS_ROOT + "/public/data/csv"
directory for any files.  Presently,  the directory has none.
Consequently, "aHashes", an array of hashes in line #112 should be
empty.

That is indeed the case, as evidenced by the logger msg from line 113
appearing in  the Command Window running Mongrel.

Therefore I expect lines 114 & 115 to be honored, i.e. nothing to
rendered and the index method to be invoked.

Instead, I get:
Missing template csvs/startup.erb in view path K:/_Projects/Ruby/
_Rails_Apps/PayrollApp/app/views:

Why is the app attempting to render something I don't expect ever to
happen?  (If I do find files,  I'll insert their attributes in the
database and redirect to index.

Where am I going wrong?

Thanks in advance,
Richard

 From the website I take it to mean there is a category for a business  
or enterprise which depends in a large part on Ruby, and also a  
category for activity which has increased the prevalence of Ruby.

[Rails] Re: Git workflow

[Miles Georgi]

I would just create the bare repository, and then push to it.  It's
pretty straight forward, something like:

mkdir project.git
cd project.git/
git init --bare

Then go to where ever you have an up-to-date branch in a repository

git push somemachine:/path/to/git/repos/project.git master

you should definitely be using git with capistrano instead of copying
working directories, yikes

when people push seperately, they have some options.  The most
straight forward is to do a pull before doing a push.  That way it
merges any commits that you're missing.  Even better is to use rebase
so that it always looks like a fast-forward push (ie, your history
isn't full of merges that exist solely to get the lastest changes
since your last pull.)

you'll probably have to read up on some of these concepts.

Thanks for that Miles.

I had seen stuff about 'bare repositories' but didn't know what they
were.

Does an auto merge happen if two people push separately?

Can I convert my server repo to a bare repository or should start
again?

Might have to change my Capistrano deploy as currently it does a file
copy from the repo folder rather than via git

[Rails] Re: Saving a "final" version of a record.

[Michael Kahle]

Thank you Robert and Patrick for such thought provoking posts.  Notice 
how both of you are saying similar things to what Ar first suggested?

> Ar called it a "before_save callback function."
>> Robert suggested, "I suppose I could have done the update 
>> automatically on save depending on the state of the claim.
>> But, I chose instead to allow the user to update at their 
>> own discretion."
>>> Finally Patrick thought of the copy-on-write feature.

This got me thinking about rsync, or git; even Apple's Time Machine. 
All of these programs store data in a "state" that allows you to view 
the changes over a period of time.  What is this design pattern called? 
Has it been written about?

The software we use to run the business where I am employed has 
something like this on the accounting side.  The whole, "close out the 
month", feature.

Humm...

[Rails] Re: remote_function in IE with select input onchange

[hyuan]

Curious, how was the onchange event generated?  Did you use
remote_function?

It's been a while since I've used prototype for these calls - but I
know for a fact that this works using the jrails plugin and just
adding an onchange event to the pulldown via jquery and
remote_function.

Hm, if you already have apache, why to make so complicated stuff

[Rails] Re: Params error with: complex form+multiple models

[David Sousa]

Hi Hassan Schroeder,
thanks for replay it.

So, to solve the problem I had to create a unique ID to each element.
That was easy I used this code:

<% fields_for "invoice[items_attributes][#{Time.now.tv_usec.to_s}]", 
invoice_item  do |form_invoice_item| -%>

And with Time.now.tv_usec.to_s I created a unique ID for each group of 
elements, and e got the params hash like this:

Parameters: {"commit"=>"Cadastrar", "invoice"=>{"mode"=>"in",
"items_attributes"=>{ "239625"=>[{"price"=>"2", "should_destroy"=>"", 
"quantity"=>"2", "id"=>"109", "item"=>"2"}],
  "48717"=>[{"price"=>"5", "quantity"=>"5", 
"item"=>"5"}],
  "238297"=>[{"price"=>"1", "should_destroy"=>"", 
"quantity"=>"1", "id"=>"108", "item"=>"1"}],
  "240939"=>[{"price"=>"4", "should_destroy"=>"", 
"quantity"=>"4", "id"=>"110", "item"=>"4"}],
  "236847"=>[{"price"=>"3", "should_destroy"=>"", 
"quantity"=>"3", "id"=>"107", "item"=>"3"}]},
"total"=>"123", "id"=>"45", "company_id"=>"10"}, 
"authenticity_token"=>"560d84898abf599368ad8ef6972ffbb649ecf0ee"}
( http://pastie.org/340083 ).

But I got a problem when accessing those attributes in  my model.
It was like this:
...
items_attributes.each do |attributes|
  invoice_item.build(attributes)
...
and I have to add a [1] to access the right attributes.
...
items_attributes.each do |attributes|
  invoice_item.build(attributes[1])
...

The attributes[0] give me = 239625, and
attributes[1] = price2should_destroyquantity2id109item2

To create I new record, every thing was ok.
To edit, I have to access the ID of the attributes variable... and I 
don't know how. I have tried attributes[1][:id], attributes[1][0], 
attributes[1][id].
Nothing seems to work. My model source code is here: 
http://pastie.org/340088

So to sum up, how can I access the Id attributes of attributes[1]

Thanks

David Sousa

[Rails] Re: Git workflow

[Miles Georgi]

generally, what people do is use a "bare" repository as the main
repository.  A bare repository has no working directory, and thus
doesn't have this issue.

[Rails] Git workflow

[giorgio]

Hi,
Can someone answer a couple of Git questions that are puzzling me?

I have a repo on my Linux Server
I 'git clone' the repo on my laptop (xp)
I do some stuff
I do a 'git add .' and a 'git commit -m "some comment"'
I do a 'git push' to the remote origin (Linux server)

Here is where it gets confusing...
On the Linux repo the "index" is updated but not the "working tree"
I have to do a 'git reset --hard' in order to see the laptop changes
on the server.

The question (finally) is:
what do I do if several people are trying to push to the server?. I
cant do a reset --hard as I will lose any changes somebody else has
made.

What happens on GitHub when several people push to a repo?

I cant seem to find anything in the doco. Doing a pull or fetch/merge
from the remote repo seems to be the recommended method but GitHub
appears to use 'pushes'.

Can anyone enlighten me or point me at some articles that may help.

Thanks
George

[Rails] Re: Modify Session Data using session_id

[Jeff Vogt]

I just realized that since the objective is to modify another user's 
session data (as opposed to my own), the code I am using will work. 
There's one caveat, however, and someone correct me if I'm wrong:  If 
the user who's session data we are changing makes a request at the exact 
same time as our user who is modifying data, there's a chance that he 
will overwrite our changes, and there is no easy way to detect this.  Or 
is this not true in a single-threaded environment?

That being said, I'm also slightly embarrassed to post the following 
code, I have a feeling there's a much better way to do this.  But here 
goes:

@@connection ||= ActiveRecord::Base.connection
record = @@connection.select_one("SELECT * FROM sessions WHERE 
session_id = '#{other_sess_id}'")
a = record['data']
b = Marshal.load(ActiveSupport::Base64.decode64(a)) #demarshal and load 
session into b
b[:testdata] = 'data here'
c = ActiveSupport::Base64.encode64(Marshal.dump(b)) #marshal
@@connection.update("UPDATE sessions SET data = '#{c}' WHERE session_id 
= '#{other_sess_id}'") #save to db

Thanks for the reply.

I played around with process_cgi and determined it wouldn't work for 
this application.  Further, I went into the code for action_controller 
to see how session data is saved.  I went as far as writing my own 
method that repeats the exact way session data is saved in Action 
Controller, but no dice.

What I think is happening, is when a request is made by the client, it 
grabs the current session data for a given session_id, THEN executes 
application code (including updating in memory any changes to the 
session data, THEN updates the database.

When we force changes to the session (by selecting sessions.data by 
session_id, modifying, and saving) INSIDE of a request routine, the data 
changes just fine, but is overwritten at the end of the request.

I think.

If anybody has an idea to access whatever is the temporary store for the 
session when it gets changed during a request, I'd love to figure this 
out.

Sorry to bump a fairly old thread.  I was searching for a slightly 
different question and saw this post, which I might be able to help 
with.

If you are planning to have the label printed at the client computer, 
and it is running Windows, UPS provides a plugin for FF and IE that will 
immediately print a label fed to it by the server, no questions asked. 
(Secure, I know.)  The way they've used it on the UPS site is within 
embed tags.  Since the plugin doesn't display anything, you'll want a 
HTML response with that embed tag in it, rather than sending the EPL 
data alone as a response.



The UPS EPL plugin can be found at http://tinyurl.com/6mpohy


If the client may be running Linux, you can make a script that can be 
associated with EPL files, which simply opens the serial device and 
sends the EPL data as is.  If you'll be printing labels at the server, 
and it's Linux, you'll do it about the same way, but printing through 
lpr with an unfiltered/raw device would be a bit smarter there.

If you want to print labels at the server and it's a Windows server, 
you'll need to open "LPT1:", "COM1:", or "USB001:" as appropriate and 
feed the EPL data there.

Hope this is helpful to you or anyone else searching on the subject!

[Rails] Newbie installing EdgeRails: Error

[Michael Franzl]

Hi,

I'm using Ruby-1.8.7, Rubygems-1.3.1, Rails-2.2.2 and 
Rake-0.8.3.

But getting EdgeRails via

 rails test
 cd test
 rake rails:freeze:edge

yields

 rake aborted!
 wrong number of arguments (2 for 1)

What is wrong with this? The same error pops up with 
Rails-2.2.1 in combination with Rake-0.8.1.

Hints appreciated!

Michael

I wonder if you could implement a "copy-on-write" feature in the Customer,
Registration, Dealer, etc... tables.  Basically, add a "freeze_record"
boolean column to those tables and set that to "true" when you need to
finalize one of those records.  If you ever want/need to update a frozen
record, you could allocate a new one, scan all of the claims to which this
record "belongs_to" and point all of those that are not closed to the new
record.

This strikes me as an ideal candidate for some sort of plugin that mixes
into ActiveRecord.  Unfortunately, I haven't the foggiest idea how to
implement the practical side of this theoretical solution (yet... but I'm
learning more every day).

Hello,

I am trying to figure out how to export to a csv.  I have found lots

[Rails] insecure: can't modify hash

[Gregory Mirz]

A weird problem occurs (only on the prod server, not locally), when i
try to register a new user with restful_authentication.

Once in a while, i get the following error when trying to sign up as a
new user:

Insecure: can't modify hash

usr/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active_record/attribute_methods.rb:309:in

/usr/bin/mongrel_rails:16

Im really clueless on what's causing it. Even more strange is that it
doesn't right after a fresh deploy, and it doesn't happen locally. My
first reaction was to run rake db:sessions:clear in case there was some
unwanted persistence in the sessions, but it doesn't seem to come from
that...

If any knows about that error and could help... thanks :!

[Rails] conditional delete of a session

[James Byrne]

Rails 2.2.2
Ruby 1.8.6

ActiveRecord Session Store enabled

For testing purposes I wish to ensure that no session exists.  To

  session.delete if session

But this fails if session == nil and I suspect that it does not work as
I anticipate if session exists.  In the console I see this behaviour:

$ script/console

Michael,

I completely understand your dilemma. I spent quite a bit of time on a 
claims application myself. I can tell you that your statement, "This 
could get messy." is certainly true. Unfortunately, I don't know any way 
around it not being "messy." I don't know of any plugins or such that 
would help here, but maybe there are some.

The approach I took was to treat models related to the claim as 
"templates" for filling in the claim records. In my case this system was 
for the trucking industry. So I had to deal with information about truck 
drivers, claimants, insurance companies, etc.

My system would capture a "snapshot" of a driver (for example) and copy 
that data to a separate table that was then related to the claim. Then I 
provided a way for the user to update the driver's data in the claim to 
the latest version in the original driver record, but only if the claim 
was open. Once closed the update feature was no longer available.

I realize this is not ideal, but the alternative wasn't much better. I 
suppose I could have done the update automatically on save depending on 
the state of the claim. But, I chose instead to allow the user to update 
at their own discretion.

In my case some of the data needed to be captured (and frozen) based on 
the date of loss. We needed to know the driver attached to an order on 
the date of loss. So even if the order was assigned a new driver we 
still needed to capture the original driver's information that was 
involved in the claim. Which meant that is data had to be frozen when 
the claim was created, not when it was finally closed.

[Rails] form for

[Maulin Pathare]

I have two models, ladder and statistic
The relationship is
ladder has_many statistics
statistic belongs_to ladder

In a view for my ladder controller action show, I am redirecting the
user to an action in my statistics controller using

<% form for ladder_statistics_path(@ladder) do |f| %>
  <%= submit_tag 'Create' %>
<%end%>

I would think that in the statistics controller the object @ladder and
all of its attributes would be available to me, but only the id is
available in the params hash as params[:ladder_id]

I have to explicitly call

@ladder = ladder.find(params[:ladder_id])

in the statistics controller to get @ladder.name

is this normal, or am I doing something wrong?

[Rails] Expire_fragment in observer/model? Works fine in Sweepers.

[Marston A.]

I've pretty much tried everything, but it seems impossible to use
expire_fragment from models?  I know you're not supposed to and it's
non-MVC, but surely there much be some way to do it.

I created a module in /lib/cache_helper.rb with all my expire helpers,
within each are just a bunch of expire_fragment calls.  I have all my
cache sweepers setup under /app/sweepers and have an "include
CacheHelper" in my application controller so expiring cache within the
app when called via controllers works fine.

Then things is I have some external daemons and especially some
recurring cron tasks which call a rake task that calls a certain
method.  This method does some processing and inputs entries into the
model, after which I need to expire cache.  What's the best way to do
this as I can't specify "cache_sweeper" within the model.

Straight up observers seem to be the best solution but then it
complains about expire_fragment being undefined etc etc, I've even
tried including the ActionController caching classes into the observer
but that didn't work.  I'd love some ideas of how to create a solution
for this.  Thanks.

Hi, we use the same plugin at https://www.digiprof.fr/login, we 
experienced the same problems. The main gotcha, is that you are 
certainly using some_resource_path in your link_to instead of 
some_resource_url.

Because with _path, the protocol used is the one of the current page 
because it actually generates relative paths. Using _url, the protocol 
of the page generated can be different as it generates absolute paths.

Have you also edited routes.rb to add the correct protocol?

Are you running the same configuration in your dev environment?
If not, can you try it, or alternatively try uploading directly to one of

Seems like the first thing to try to eliminate from the equation :-)

[Rails] Re: HTML in db columns

[Robert Walker]

It sounds to me like your HTML is getting sanitized somewhere, which is 
actually a really good thing. Allowing raw HTML to be passed though from 
an input (textfield, textarea, etc.) and then displayed without being 
sanitized can lead to all sort of security problems.

My recommendation would be to look into supporting Textile/Markdown in 
your input textarea and make sure you are properly sanitizing your HTML. 
Otherwise, you may leave yourself open to cross-site scripting or SQL 
injection attacks.

[Rails] Third Party Tool for Business Directories?

[JimCifarelli]

Hello again Rails Community,

I'd like to add a subscription based "Business Services Directory" to
a Rails app so that other businesses can advertise under a "category".

This site currently uses third party tools in many views to offer
event calenders and for taking polls.

Is there a third-party service (like for calendars or poll questions)
for this paid directory listings/search/sign-up service?

I know I've seen outsourced "Knowledge Base" functionality so that one
could include a knowledge base within their site.  What I need is
similar in practice but different in content.

Thank you for your time.


Sincerely,
Jim

[Rails] Re: Scaffold leads to OK database, but model empty

[Robert Walker]

>>> @csv = Csv.new
> => # imported: nil, created_at: nil, updated_at: nil>
One other thing that might be noteworthy...

Notice how your "created" and "modified" attributes are redundant with 
"created_at" and "modified_at." You might want to consider using the 
ones provided by Rails by default. This way you have no additional work 
in updating these standard fields. Rails with take care of them for you.

Then you also have the "imported" attribute. Since this is also a date 
field you might want to follow the Rails convention for naming date and 
time fields by appending "_at" or "_on" so you could have "imported_on" 
if you want a date only or "imported_at" if you want to also record the 
time along with the date.

Also note that the default attributes added by "t.timestamps" in your 
migration will use date and time, but you can always format your view to 
show date only if you want. And, of course, you will need to update the 
value of "imported_at" yourself since it not something Rails can do 
automatically.

[Rails] Re: ActiveRecord Oracle and nvarchar2 or nclob datatype

[mrbana...@googlemail.com]

Just in case somebody is facing this issue as well...

It seems that ActiveRecord is not handling oracle nvarchar2 column
types correctly.


If somebody is facing my issue: Please find beloa the code for a fix
Many thanks to the oci adapter engineer who did the main work for it.

module ActiveRecord
  module ConnectionAdapters #:nodoc:
class OracleColumn < Column #:nodoc:
  attr_reader :nchar
  def initialize(name, default, sql_type, null)
super
@nchar = (@type == :string && sql_type[0,1] == 'N')
  end
end

class OracleAdapter < AbstractAdapter
  def quote(value, column = nil) #:nodoc:
if value && column && [:text, :binary].include?(column.type)
  %Q{empty_#{ column.sql_type.downcase rescue 'blob' }()}
elsif value && column && column.nchar
  'N' + super
else
  super
end
  end
end
  end
end

Thanks.  I was hoping I'd discover something of "The Rails Way".

[Rails] Linking in SSL page to non SSL

[Nik B]

I have a situation where I am generating links in an SSL secured area
(no subdomain) to a non SSL page (with a subdomain). The certificate
doesn't cover subdomains, so everytime someone clicks on the link to a
https:// page where SSL isn't allowed there is a certificate error.

Now users can click okay, and then they are redirected to the http://
page, but I would like to create the link directly to http:// rather
than https://

I'm using the ssl_requirement plugin. Is there a way to do this?

Thanks,
N

Absolutely, that's basic HTML -- an ID must be unique within a given
page. And more so if you have JavaScript acting on things via ID.

Exactly, and

..probably worth mentioning that you can easily confirm something
like this by opening your Rails console and entering e.g.
   @csv =  Csv.new
and viewing the output.

[Rails] Re: Params error with: complex form+multiple models

[David Sousa]

So, now I know where is the error, but I still don't know how to fix it.

When I use remote_form_for, the params hash gets messed up. If I use, 
form_for, everything is sent ok. But, I want a Ajax for.

Does anyone know how to fix it?

thanks,

ActiveRecord automatically discovers the fields in your model's table
and creates accessor methods for you at runtime, so the model shown is
all you need.

[Rails] Multiple Models, one form, has_many AND has_one not workink

[Darran Thompson]

I have a model (Employee) which has a has_many association with
(FlatMate). A flat mate also has a has_one association (PrimaryAddress).
Now when I try to create a form and then submit it I receive the 500

Can anyone help me out?

[Rails] Scaffold leads to OK database, but model empty

[RichardOnRails]

Hi,

I ran:
ruby script/generate scaffold Csv filename:string created:date
modified:date imported:date
rake db:migrate
sqlite3 db\development.sqlite3
.dump csvs (database columns displayed as expected)
type app\models\csv.rb (which displayed only:
class Csv < ActiveRecord::Base
end
with no field names)

I'm inclined to just populate the latter with:
@filename,  @created,  @modified,  @imported

Is this the way to go,  or is there some "Ruby Way"?

I'm running:
ruby 1.8.6
Rails 2.2.1

Thanks in Advance,
Richard

[Rails] RoR survey (research of the Utrecht University)

[Maarten]

Dear Rails developers,

On behalf of the Utrecht University (in the Netherlands) I would like
to invite you to complete a survey on your perception of the Ruby on
Rails framework. The goal of this research is to design a model that
explains and predicts the adoption of Ruby on Rails by web application
developers in the enterprise environment.

The survey is aimed at professional web application developers.
Experience with Ruby on Rails is not necessary.

The survey consists of two pages of questions and it will take less
than 10 minutes to complete it. You can participate anonymously or you
can choose to leave your email address at the end of the survey if you
would like to receive a copy of the final results of this research.

The survey can be found here: www.cs.uu.nl/survey/ror

I would really appreciate it if you would help me finish my thesis
research. Thank you!

Kind regards,

Maarten Nefkens

[Rails] API versioning strategy

[Zac Zheng]

I am developing a service to be accessed within a browser and via API. I
am not sure what the best practise for API versioning is.

AdWords API split into major version by URI mutilation: /v1, /v2 etc.

My current thoughts are:

Website accessible from www.myservice.com
API accessible from v1.myserviceapi.com This will be a separate instance
with its own mongrels/mod_rails.

Major updates will go under a incremented subdomain,
v2.myserviceapi.com. This will happen infrequently. Perhaps once a year.

Minor updates will be a normal capistrano deploy.

Can anyone please comment on the above? It's much appreciated.

Zac

"bullets" are a visual attribute of OL/LI defined by the page's CSS; are
you sure your style sheet isn't overriding the default browser view, or
causing the bullets to be hidden by another element?

OTOH, if you can't see the OL/LIs in a page via `view source` I think
you'll need to post some code.

You could use a type column, and single table inheritance, but I suggest 
creating a separate Author model with its own authors table, and have a 
user_id in that table. This way, an Author belongs_to a User. All 
author-specific data goes in the authors table, and you can reuse all of 
your authentication with the User model.

Alternatively, users could have an author_id, if that makes more sense.

[Rails] Doozy of a pagination problem

[Joe Peck]

Hey,

This is sort of complicated, and I'm trying to keep it as simple as I
can.

I'm using will_paginate to display only 25 snapshots on each page.  My
question is how can I return only the most recent snapshot per link
(just one per link)?

@snapshots = Snapshot.paginate :order => 'snapshots.weighted_score
desc', :conditions => ["snapshots.scenario_id = ? and (links.status = 1
or links.status = 2 or links.status = 4)", @scenario.id], :include =>
[:page, :link, {:snapshot_attributes => :attribute}], :page =>
params[:page], :per_page => 25

Let me know if any other information is needed, and thanks for any
advice.

> In all my humble newbieness, it looks to me like, when you get a URL of the
form /roles/something?with_this?and_that, the first pattern that the route
table finds that matches that is the pattern that looks like: /roles/:id, so
you get routed to the "show" action of the "roles"controller.  I know that
the routes table is processed in order and the first pattern that matches is
the one that triggers the action (which is why the /:controller/:action/:id
pattern is always listed last.).

What I don't know is, why does {:action => "remove_role_from_account",
:role_id => role, :account_id => @account} produce a url of the form:
/roles/remove_role_from_account, when you specifically plug in an action of
"remove_role_from_account".

Sorry if this doesn't help much.

Yes, but the problem was with my code, not his.

  def new
@user = User.new(params[:user])
if @user.save
  flash[:notice] = 'User Account Added'
  redirect_back_or_default account_url
else
  render :action => new
end

Should have been.

  def new
@user = User.new
  end

Somehow I ended up coding a create method and labelling it as new.

Thanks Fred.

This is exactly what I was looking for.  You might also want to point 
out that you can also do this

@person.attributes.to_options!

That will symbolize the keys, to make it look like the params[] field 
that is passed to the controller

seeing this error, in my logs:  (see stack trace below)  it appears
that the body of some of my requests are null... I'm trying to figure
out if a) it's a rails issue, b) is it a jruby/rack issue or c) is it
an issue with caching (which is turned on but I wouldn't think should
be an issue on a login/logout scenario).  any one have any thoughts on
where I Could check to see why the body is null?  I'm off to try and
turn off caching to see what happens but this issue is a pretty big
issue and we need to resolve it asap.  We see it in normal usage of
our website too.  It appears to be timing related but I'm not sure why
or how yet.

I'm not necessarily looking for THE answer but any general help of
"check xxx" would be great.

Thanks!
Jay

[Rails] Re: finddef - find methods in textmate

[jzimmek]

both provide a find-method functionality (and rubyamp a lot more).

i am not very familiar with rubyamp, but looking at the code i see the
following difference:

finddef:
uses the "selected word" / "cursor position" to lookup the method
definition by pressing "^-"

rubyamp:
prompts you for a "methodname" to search for

imho is pressing "^-" much simpler than entering a complete methodname
to search for.

finddef will find method definitions in the open project, rubygems and
in an usersupplied searchpath if you wish - i have not used rubyamp,
so i do not know if this is a difference between the two.

[Rails] user + author in one model or not

[Petr Bobek]

Hi everybody,

I am building some kind of social networking web. I have implemented
user registration and now I would like to add another type of
registration (authors). I dont know whether to keep the registration
simple and add just a checkbox (user and author) and add a new column
(user_type) into the existing user table or build a new model
Author to manage authors.

Thanks for your thoughts.
Cheers
Petr

[Rails] Unicode problem with mb_chars.index

[Peter]

Hello,

I tried the following
str ="ÄÄa__"
assert str.mb_chars.is_utf8?
assert str.is_utf8?

# this is logical
assert_equal 4, str.index("a", 4)

# this is not logical. shouldn't this be nil !?
assert_equal 2, str.mb_chars.index("a", 4)

Why is the last line failing? And how could I fix this?

Regards,
Peter.

[Rails] Re: Modify Session Data using session_id

[sadeesh kumar viswanathan]

Hi,
Rather than accessing a base methods directly, you can access some
class methods like 'process_cgi' to solve you pbm better I think. Try
http://api.rubyonrails.org/classes/ActionController/Base.html#M000523
this one and post here whether it helps you or not. I am also
interested in knowing this.

Thanks,
Sadeesh

great - interesting how I've been using the "transaction" model for some
months but it is only since I've had a new model that has an association
with it (i.e. the "allocation" model in this case) that I've noticed an
issue...  :)

[Rails] Modify Session Data using session_id

[Jeff Vogt]

Hi, first post here.  I'm enjoying getting to know rails.  I have been
scratching my head trying to find a way to modify data in a session by
directly accessing CGI::Session.

I should note, using the following code, I can successfully create a new
key / value pair from the console, but not within my app.  I have tried
both methods below:

def add_session_data(other_sess_id, new_data)
a =
CGI::Session::ActiveRecordStore::Session.find_by_session_id(other_sess_id)
a.data[:test] = new_data
a.save

[Rails] Asset timestamping and images referred in CSS

[Piotr Wlodarek]

Rails appends ?mtime to asset paths, which is nice.

But how to coupe with images referred in css? Example:

background-image: url(../images/bg.gif);

Idea? Plugin?


Regards,
Piotr Włodarek

[Rails] Re: routes.rb

[Franz Strebel]

and don't forget that you can use rake routes to see all your
available routes at any given time, and their corresponding
controllers and actions.

[Rails] Re: routes.rb

[Thorsten Müller]

If you nest your resources as you do, then
the url will need all parts of it like:

user_role_path(@user, role)

As parameters it takes the resource ids as default,
so you don't need the :id and the :user_id here

map.namespace :api do |api|

[Rails] Routing Problem please help

[Sameera Gayan]

Hi all,

I'm creating a REST API for one of my projects and I'm stuck in a
routing issue.

I have a resource called mobileowner (which will send the user xml when
given the mobile no)

And my controller is in the following path

app -> controllers -> api -> mobileowner.

so can someone tell me how to configure this in my routs.rb file. (to
work mobileowner as a resource).

I'm using rails 2.0.2

thankx in advance

cheers
sameera

[Rails] routes.rb

[Mark Moore]

Hi,

I am going through a tutorial in a rails book. I have Something off with
routes:
I have RESTful resource in routes.rb:

"...
  map.resources :users, :member => { :enable => :put } do |users|
 users.resources :roles
 end
..."

and in a html.erb partial I have:
"...
<%= link_to 'assign role',
role_url(:id => role.id, :user_id => @user.id),
:method => :put %>
..."
I get:
 NoMethodError in Roles#index

Showing roles/_role.html.erb where line #9 raised:

undefined method `role_url' for #

I might be using newer version of rails than the book.  The role_url is
not an explicitly defined route in this tutorial routes.rb file, I don't
know enough about RoR, but I am guessing the role_url should be
automatically available, so I would appreciate any help with this
because my RoR learning is halted here.
Cheers,
Mark

[Rails] Re: marshal data too short

[Benjamin Bonnet]

Hi, I ended up with this problem, but having a six hundred thousands 
records in my sessions table…
Surely've been hacked;
The site are protected with a simple login page (salt & hash, successful 
create a user session) and is just on the web for development/production 
testing.
I wonder exactly how it has happenned; The logs don't show any 
activities !!!
might be something like XSS, but if it seems obvious for some of you, 
thanks for the info you'd provide.
