[Rails] attr_accessor as boolean
Hi I have in my user model attr_accessor :no_password_validation_needed with_options :unless => :no_password_validation_needed do |p| p.validates_length_of :password, :minimum => 6 p.validates_confirmation_of :password end And from controller I do @user.no_password_validation_needed = false @user.update_attributes(params[:user]) And it works perfectly and now validation happens. If it is @user.no_password_validation_needed = true Then also I get the expected result as now validation not happens But now when @user.no_password_validation_needed = 2 #or any other value Now I get unexpected result as validation not happens That is same result when true? Why this?What modification should I make?Please help Thanks in advance Tom -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] virtual/dynamic tables?
Hi, I'm trying to figure out a way for my users to create their own forms and store the data collected into their own customized table. For an example (though unlikely), say they want to create their own variant of an address book. They specify the fields, some field requirements (unique, size limit), perhaps a regex expression (possibly from a list of examples) to validate the data, then I create the forms for creation/update and the views for browsing, searching, deleting. Is there a plugin or example out there that can help with something like this? For dynamic creation of the storage, I was thinking of an architecture like so: 1. VirtualTable: * name:string * user_id:integer 2. DataColumn: * virtual_table_id:integer * name:string * data_type:string * limit:integer * regex_validator:string * unique:boolean 3. DataRow * virtual_table_id:integer * created_at:datetime * updated_at:datetime 4. DataString * data_column_id:integer * data_row_id:integer * data_value:string 5. DataText * data_column_id:integer * data_row_id:integer * data_value:text I'm guessing I'd have to put most of the CRUD logic in a single model, perhaps called VirtualData. Hopefully, the controller can just do something like VirtualData.create params, and the magic happens inside the model. I haven't worked out the details there yet. Is there a better way? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] form_for with nested shallow route
Let's say I have: map.resources :teams do |team| team.resources :squads, :shallow => true end When I want to generate a form_for a squad, I need both the team and squad for new/create, but only the squad for edit. This means I need: edit: form_for(squad) new: form_for([team, squad]) This seems not very dry. Is there a more idiomatic way of doing this? Right now, I've abbreviated to: form_for(team = team ?

[Rails] Re: need to parse a User uploaded file, but don't care if it's saved
@Luke: Thanks! Yeah, I saw that tutorial, too. But, also like you
said, it still saves it to a model, so I'd rather just let paperclip
handle all that. Thank you anyway though.
@Jeff: Thank you!
For full disclosure, I'm still a little bit of a noob to Rails (and
ruby) but I think I get more than the gist of your code. So,
definitely a big thanks.
I do have a couple questions as to what's going on though. Like I get
that the file is read, along with its contents, but where is it read
from? Like, is the file actually uploaded to a temp directory, and
you're saying that I just don't have to expressly mess with that
directory? Or, is it just held in memory in a Rails process
somewhere? Might that be worse than just storing the file, then
deleting it later?
I'm just asking, I honestly don't know. Also, while the file uploads,
a Rails process is not tied up, correct? It's actually being buffered
by the server?
A big thank you Jeff, and to anyone else that wants to chime in. I
think this is definitely a huge start down the right path.

respond_to do |format|
if @request.save
flash[:notice] = 'Request was successfully created.'
format.html { redirect_to requests_url }
format.xml { render :xml => @request, :status => :created,
:location => @request }
format.json { render :json => {:result => 'success', :redirect
=> requests_url } }
format.js
else
.
once the request is saved, ... I get in the log

if (json.redirect) {

[Rails] Upcoming app > Research and Prep
Hey everyone. I'm a one person team and in the next month need to produce and deploy an application. I've been playing with rails for a little over a year now and recently deployed my first app as a private contract. I'm now planning development on a start up company. The app should be expecting high volumes (not like Twitter but high for sure. Its no social media app) My target audience is very specific but in certain locals the app has been requested by many users who are in fact waiting for the app to deploy. Smaller Volumes actually uploading files and adding objects to the db. Many people surfing the site. (Probably the same sort of RATIOS as cragslist (posters:readers, but not near the volume.) My current plan is and I need some help with this: Start on shared hosting unlimited traffic/storage. Will move to dedicated-virtual if shared hosting causes performance issues when traffic picks up. Behavior Drive Development via RSpec & Cucumber. Build the App in rails with ActiveRecord (I read somewhere ActiveRecord can be swapped out for something faster, Should I use something else?) Use multiple MySQL databases 1 master for writing, at *least* 2 slaves for reading. (Any info on this would be good.) Run multiple mongrel instances via mongrel_cluster. (How many is sufficient? I think currently I have 4 available on my hosting, can upgrade later if needed. So that would be 1 main instance and 3 extras.) Paypal via Active_Merchant for all payment processing. (May accept money order and check but that's not app related.) Amazon S3 services for file/image upload & hosting (Via paperclip.) I may start by hosting all images from local server as I have unlimited space but I feel as the app grows my hosting may not appreciate the traffic and I'll move to Amazon S3. Deploy via Git & Capistrano I'm going to do all the base functionality for the application myself. Get it running get people signed up get them using the app. Hopefully the multiple db's and mongrel instances should supply enough speed to start. At which point if everything goes as planned (it never does) I'll outsource and get added security. Get queries optimized and work on overall performance via back end processes etc that will be over my head for sure hence the outsource or hire of private team. I know at this point it will be necessary to do these things and costs for such have been accounted for. Any help with gathering resources where I can find more information about the above topics or personal experiences would be greatly appreciated. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: [Rails] :has_many and :controller specified in routes.rb
Maybe you could use:
map.resources :buckets, :controller => 'v1/buckets' do |buckets|
buckets.resources :apples, :controller => 'v1/apples'
end
I know this is a bit more code than just using :has_many, but I don't think
:has_many lets you specify a different controller.

Apache user is www-user anyway, not root. Root user is only for the master process. you should change the ownership back on all files/folders in /home/justinscheier/www/testapp1 Then, you need to indicate in your apache configuration which RailsEnv is to be used...

hmm yeah that's what I meant. Thanks I think I figured it out.
This is the code I will use in the routes.rb file:
map.admin 'admin.:format', :controller => 'user_sessions', :action => 'admin'

By the way do you know how I can get the "format.csv { render :csv =>
@logs }" part to work? I have tested it on an index page and that
works, but when I try it on this admin page it says it doesn't
understand the URL. I have set a direct path to the admin page instead
of the standard "controller/action" path in the routes.rb file, but
even if i go through the "controller/action" path it still says it
can't find it. Is it because of that direct path in the routes.rb that
it's giving me the error?

[Rails] Re: submit form in popup and send value back to the main page
I added some javascript to the create.html.erb template that opens in
the popup after the document form submits.
The javascript is supposed to close the popup and send the title of
the document back to the main page but it's not working. Anyone know
why?
this is what is in the create.html.erb template:
function copyData(){
var docField = window.opener.document.getElementById('title');
docField.setValue('<%=h @doc.title %>');
this.close();
}
copyData();

[Rails] :has_many and :controller specified in routes.rb
Have an app using older version of Rails (2.3.2) that I need some
routing assistance with if anyone has a minute.
The app was originally designed to be purely html view, and an xml and
json api was hacked on. To keep it clean, we are now moving the first
version of the api (v1) under its own directory (v1) under app/
controllers but still responding to the old paths.
One of the parts of the new routes.rb specifies:
map.resources :buckets, :has_many => :apples, :controller => 'v1/
buckets'
However, when I do rake routes, this produces:
...
buckets GET /buckets(.:format) {:controller=>"v1/
buckets", :action=>"index"}
POST /buckets(.:format) {:controller=>"v1/
buckets", :action=>"create"}
new_bucketGET /buckets/new(.:format) {:controller=>"v1/
buckets", :action=>"new"}
edit_bucket GET /buckets/:id/edit(.:format) {:controller=>"v1/
buckets", :action=>"edit"}
bucketGET /buckets/:id(.:format) {:controller=>"v1/
buckets", :action=>"show"}
PUT /buckets/:id(.:format) {:controller=>"v1/
buckets", :action=>"update"}
DELETE /buckets/:id(.:format) {:controller=>"v1/
buckets", :action=>"destroy"}
bucket_apples GET /buckets/:bucket_id/apples(.:format)
{:controller=>"apples", :action=>"index"}
POST /buckets/:bucket_id/apples(.:format)
{:controller=>"apples", :action=>"create"}
new_bucket_apple GET /buckets/:bucket_id/apples/new(.:format)
{:controller=>"apples", :action=>"new"}
edit_bucket_apple GET /buckets/:bucket_id/apples/:id/edit(.:format)
{:controller=>"apples", :action=>"edit"}
bucket_apple GET /buckets/:bucket_id/apples/:id(.:format)
{:controller=>"apples", :action=>"show"}
PUT /buckets/:bucket_id/apples/:id(.:format)
{:controller=>"apples", :action=>"update"}
DELETE /buckets/:bucket_id/apples/:id(.:format)
{:controller=>"apples", :action=>"destroy"}
...
(sorry for the bad formatting)
Notice that the routes for the actions specific to the model
referenced by :has_many ignores the specification of the controller
(they go to :controller=>"apples" instead of :controller=>"v1/
apples").
Sorry for the n00b routing question. I didn't find such an example of
how to set the controller of the :has_many referenced model yet, but
maybe it is an option somewhere, or I could setup another route for
that?

[Rails] Rails 3 + Different ORM
I'm migrating an old project (not Rails) over to Rails 3. I've been using Sequel as my ORM and I'm quite happy with it. However, when I add Sequel models to my app/model directory, they don't seem to load on their own. Am I going to need to load them manually or do I need to set some kind of configuration option somewhere? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] submit form in popup and send value back to the main page
I made a popup within object1's form to show another form to create a new document object to associate with object1. When I click the submit button I want 1) the document object to be created 2) the popup to close 3) the value in the document "title" field to get added to the document name field in object1's form. I've made the form for the document object in the popup but I'm having trouble figuring out the logic for 2) and 3). I'd imagine I have to use javascript to close the popup and send the title back to the main page. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: How to reference a select_tag within a form
Thanks very much for taking another look at my problem.
> If you want to use RJS then you need
> to use the block form of button_to_function
Here's the best my brain could come up with
<%# = button_to_function("ShowList",
% ) %>
<%= button_to_function("ShowList")
{ page["vendor_droplist"].toggle } %>
but compilation of new.html.erb with that change gives me:
===
undefined local variable or method `page' for #
Extracted source (around line #17):
14: <%= f.label :vendor %>
15: <%= f.text_field :vendor %>
16: <%# = button_to_function("ShowList",
% ) %>
17: <%= button_to_function("ShowList")
{ page["vendor_droplist"].toggle } %>
18:
19:
20: <%= select_tag "list",
===
If it's not too much trouble, can you point me to website that
provides detail on the alternative forms, or even better, show me a
correct form of #17 above. Sorry for being so obtuse ... I'm a Rails
nubie, but aspiring higher :-)

[Rails] Re: Displaying a nested field as a label
This is a nested model form using to models: section and comment,
where section has many comments.
"text" is a field for comments
"approval_boolean" is a field for comments
I just want the field value for "text" to show up as a non-form-
element and "approval_boolean" to show as a check box form element.
The code above works, but I can only get the "text" field to show up
as a text_area or text_field form element.
Like I said, if <%= a.text %> worked, I'd be happy... but it gives me
a method error and I'm not sure why.
A! a.class = formbuilder. I thought it was a Comments class.
Now I know what to look up I guess my question after all is there
any way to "extract" a data value from a field within a formbuilder?
(if I got my terminology right)
Thanks for taking the time to look at this, btw.

Well what *is* your "a/comment" variable? Have you debugged it to see
what's going on in that block? Do you *know* what methods it's got, or
are you assuming there's a "text" method?
You can use <% puts %> or <% logger.info %> to output
messages to help you diagnose what's going on. Personally, I prefer to
use breakpoint debugging in Netbeans.
does 'puts a.respond_to("text")' display true?
what does 'puts a.inspect' give you?

You don't what? It is best to insert your reply at the appropriate
point in the comment so that it is easier to follow the thread. If
you mean that you don't have the .:format in the route where you are
using some_url.csv then that is the problem.

[Rails] change column to allow null

[Rails] Missing number of assertions in test output
Hi, I did a number of test runs from the book Agile Web Development with Rails, third edition, (chapter 14, Task T: Testing). I use Netbeans 6.8 as IDE. All the test output runs are missing the number of assertions. For example: |Finished in 0,733 seconds. 5 tests, 0 failures, 0 errors| However in this example, 6 assertions were tested and I expected: |Finished in 0,733 seconds. 5 tests, 6 assertions, 0 failures, 0 errors| Can anyone give me a clue why the assertions are missing in the output?

[Rails] Re: need to parse a User uploaded file, but don't care if it's saved
One way would be to just process the uploaded-file data from the
request as needed and not worry about saving or doing anything else
with the tmp-saved uploaded-file itself, something like:
### in ./app/models/uploadable_file.rb
class UploadableFile
### for use in testing:
def initialize(fname, contents)
@fname = fname
@contents = contents
end
def original_filename
return @fname
end
def read
return @contents
end
### class meths:
def self.parse(upfile)
return nil if upfile.blank? or not (upfile.respond_to?
('original_filename')\
and upfile.respond_to?('read'))
orig_fname = upfile.original_filename
contents = upfile.read
# parse/process contents
end
end
Then just call that class meth in your controller to parse the
uploaded file for an example file form element of name "upfile":
### in some controller meth that handles that multipart/form-data
form:
...
parsed_contents = UploadableFile.parse(params[:upfile])
# check results

[Rails] Frozen hash problem
I'd like to delete some records before saving them. I ran this
experiment:
before_save :prune_lab_datas
def prune_lab_datas
lab_datas.each do |lab_data|
lab_data.destroy
end
raise lab_datas.to_yaml
end
But nothing seems to be deleted in the hash:
---
- &id001 !ruby/object:LabData
attributes:
created_at: 2010-03-21 22:16:06
unit_id: "3"
lab_id: "81"
updated_at: 2010-03-21 22:16:06
id: "184"
lab_desc_id: "6"
value: "29"
attributes_cache: {}
changed_attributes: {}
errors: !ruby/object:ActiveRecord::Errors
base: *id001
errors: {}
And if I remove the "raise", the controller throws a "can't modify
frozen hash" error.
Any idea how I can remove records from the hash prior to saving?
TIA,
Craig

[Rails] Re: How do I set defaults for view parameters?
Thanks that works! I was trying params[:find_dates] == nil,
params[:find_dates].blank?, params[:find_dates] == " ", but obviously
none of them worked.
Here's an sort of off-topic question how would I go about getting
format.csv { render :csv => @logs } to work? Rails gives a method not
found error.
I did use the routes.rb file to give that admin page a direct link,
but even if I use the full "controller/action" url, it still says not
found.
Do I need to give that a direct link in the routes.rb file also or am
I missing something?

I still think you are starting off too deep in the implementation and may not have got the basic models arranged optimally. You have described what you want your application wants to do in computer terms but still have not described the real-world situation that you are modelling. For example you say "the RecipeItems technically are the recipes you might say, as the ingredients are tacked to them and there will be fields for instructions in the RecipeItem model as well". So in the real world are there recipes? If so what are their attributes? Does a recipe have Ingredients for example?

[Rails] Re: Newbie needing help on some tricky associations
Of course! Thanks very much or your replies, I really appreciate it. The app is an administrative tool, not a front end webstore. Sorry I wasn't more clear upfront, Sharagoz. The user will need to be able to create three types of items in the system via (nested model) forms: MenuItems, RecipeItems, and PurchaseItems. Ingredients are not a specific model that a user would have to interact with, as the RecipeItems and PurchaseItems are the Ingredients of other RecipeItems or MenuItems. I thought Ingredient would be an important object for the application as the name of the join model to link these items, however if another approach is recommended I am not hard set in this logic of course. The end result will be similar to many of the 'add task to project/add questions and answers to survey' nested model forms there are numerous tutorials for, but the associations just don't seem as straightforward. For a MenuItem form the user should be able to add and remove RecipeItems or PurchaseItems as Ingredients of the MenuItem (with details like quantity as well that are particular to the join). For a RecipeItem form the user should be able to add and remove RecipeItems or PurchaseItems as Ingredients of the RecipeItem (again, with details like quantity as well that are particular to the join). PurchaseItems only need to be created as they are at the bottom of the chain so to speak and don't contain other items. For example, Flour might be a purchaseitem, Pasta Dough might be a RecipeItem, and Spaghetti might be a Menuitem. Colin, the RecipeItems technically are the recipes you might say, as the ingredients are tacked to them and there will be fields for instructions in the RecipeItem model as well.

[Rails] Re: Newbie needing help on some tricky associations
It's hard for us to help you with the associations when you arent describing what you're trying to make. Im gonna try to guess based on what you've given: This is going to be a web shop with products related to cooking. A bunch of products (in this case ingredients) can be put together as a recipe. And obviously, since this is a store, a bunch of products can be put together as an order (purchase) as well. Correct? What exactly is a "menu_item"?

[Rails] Re: Adding items in groups in Rails
Seems a little odd what you are doing however to answer your question: You can add a text_field_tag or a select_tag to your form http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#M001731 e.g. <%=text_field_tag :quantity%> You can then get that via params[:quantity] in your controller from there you can either pass to your model/business logic class or do a simple: 1.upto(params[:quantity].to_i) do |i| Product.create!(params[:product]) end Personally though I would seriously consider relooking at the way you are working and perhaps normalize your data so you have 3 models: location has_many :products type has_many :products product belongs_to :location belongs_to :type Then you can do the reverse and use fields_for to add multiple products to a location.

[Rails] Re: Presentation Ideas
MVC, DRY, convention over configuration. Those are important concepts in rails. However, in a presentation a lenghtly talk about these things are probably going to be pretty boring. And its not something that student programmers may apprechiate as much as experienced programmers. I would spend a short amount of time on that and then move on to showing actual code. Stuff that looks a bit impressive, like the ajax helpers, model validation, how to interact with the database without writing any SQL.

[Rails] ActsAsTaggableOn scoped to Account
Hi, Can anybody give me some clues how to use ActsAsTaggableOn in an Account scoped way? ie. I want several accounts each to have their own sets of tags to tag their own articles rather than sharing a giant pool of tags. Or perhaps there is a better solution than ActsAsTaggableOn?

Sorry, slight mixup up; button_to creates a form, but looks like
button_to_remote doesn't. Your javscript fragment is incorrect though
- the () on a method call aren't optional in javascript, and what
you've got there looks more like RJS than javascript - the whole
page[] construct is an RJS-ism. If you want to use RJS then you need
to use the block form of button_to_function

[Rails] h() method in form partial
Hi
I have a doubt. Dont know it is valid. Just asking. I am trying to
reuse the same partial _form for both new and edit. So from new.html.erb
I call partial like
<%= render :partial => 'user_fields', :locals => {:f => f}%>
and in _user_fields.html.erb an example field as
<%= u.label :first_name,'First Name' %>
<%= u.text_field :first_name,:maxlength => 50 %>
My question is if I call this same partial in edit.html.erb also,
how can I apply the h() method like below (since this fields being
populated with value from db being an edit form)
<%=h u.label :first_name,'First Name' %>
<%=h u.text_field :first_name,:maxlength => 50 %>
Thanks in advance
Tom

Top link in google: http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/39739e012b09f97a/7364aa0c8bf5050f Read the replies about scaffolding basically you'll need to install the scaffolding gem: >From a command prompt in your app root: ruby script/plugin install scaffolding or install a previous version of rails (if you are working through a book it's probably a good idea to use the same version it uses) gem install rails -v="1.2.3" For simplicities sake probably just uninstall your current rails version (gem uninstall rails) first then install the older version; that way you'll know the rails commands are running the correct version.

Thanks for looking into my problem.
But I just noticed that there is another response on this thread.
> button_to_function creates a form, which would result in a form nested inside

Wow. As I mentioned on the other thread, I posted code on that
seemed clean from a Rails perspective and from an HTML perspective.
So, if button_to_function is inappropriate for forms, can I specify
an image that, when clicked, would toggle a page with the appropriate
id specified? Is there an example on the web that you'd recommend?
Best wishes,
Richard
