[Rails] Re: Need help for writing Api in Rails 5

[Carlos Ramirez]

Hey Tushar,

There are a lot of great resources online for creating APIs in Rails 5 
(with its new API-only mode).

One of my favorites is called *Building the Perfect Rails 5 API Only App* by 
Kam Low (which I wrote about 

).

Another that just caught my eye was this one 
 called 
*Best Practices for Designing a Pragmatic RESTful API* by Vinay Sahni. It 
isn't specific to Rails 5, but talks about API best practices and 
recommendations in general. Very comprehensive. 

Hope those help!

devise_async doesn't support Devise 4: 
 https://github.com/mhfs/devise-async/issues/94

Good news, you don't really need it, Devise has a fix to integrate with 
ActiveJob so you can remove the async gem and change your Devise model:

Are you sure you are using the same versions of gems in both
environments? I presume you have run bundle install in the production
env.

Re: [Rails] Re: Need help upgrading to Rails 5

[James Jelinek (shakycode)]

Yeah you have to specify the version number prior to the “new” verb.  I think 
this is especially important when you have multiple versions of the Rails gem 
installed on your system.

I'm experiencing the same problem.  I'm not trying to upgrade an app,

Have you been able to figure out what the problem is?

[Rails] Re: Need help upgrading to Rails 5

[raoul]

Hi Johan,

Depending on how you've configured your app, your app is probably 
suppressing detailed error messages through a config setting. Once you see 
what the exact error is, you can start to fix the actual cause.

Send me an email, I've got some time today and tomorrow and can potentially 
help you debug if you're still stuck. Firstname at prela.io

Best,
 - Raoul

What is the input you're feeding it? if the input is malformed, then 
nokogiri will have to guess at how to fix it.

This is the String#[] method 
http://www.ruby-doc.org/core-2.2.0/String.html#method-i-5B-5D 

monthname[0..-6] returns the string from the first character until the one 
6 from the end (negative indexes count from the end of strings)

monthname[3..8] returns from index 3 (i.e. the 4th character) until the one 
at index 8 

So if your string is "06 2015" then monthname[0..-6] is "06" and 
monthname[3..8] returns "2015"  (given the length of the string 
monthname[3..6] would return the same string)

Using strings that have to be torn apart like this does seem a little bit 
obtuse though.

To be honest, I don't think many people (certainly not me) want to read 
though a wall of code to work out which bits are relevant and which aren't. 
It's up to you as question asker to do extract from your application what 
is relevant and what isn't. It would however be a lot clearer if you split 
out some of this into helpers rather than having it all inline in your view

The confusing bit for me in the below code is monthname - its clearly not the 
name of the month because it's used both as an index into an array of month 
names and to extract year information - what does it contain?

What happens precisely when you click on December (what parameters are sent 
with the request and what is the code that raises an exception?)

Hi,

Resque works with Redis. Why not use Redis to keep track of executed jobs?

I think that it was rake db:migrate that gave you that error, I think
it unlikely that db:create also gave it.  If it does then copy/paste
the command and result here.

Also please remember to quote the previous message, this is an email
list not a forum, though you may be accessing it via a forum like

Re: [Rails] Re: Need help putting together a rails workflow diagram

[3dd13]

When u say u need a workflow diagram, I assume u are talking about the data
flow or communication sequence

So to help u solve this problem, one hint is
u have to illustrate how the components talks to each other when there is a
http request coming in

For example, in the case of "user wants to create a post message"
U have to write down
What data is passed from the browser to these group if components ?
Which one of these components receive the http request first ?
What information is passed from one component to another ?

Hope this help.

Maybe you should start by defining the two primary end points --
start, finish -- of the flow, and see how those pieces fit into that.

Also, it might be good to demonstrate that "basic knowledge" by
writing a 1-sentence description of the primary role of each of the

I have a basic knowledge of all of them, but the main reason of this 
task is to try and understand the logic of updating and maintaining the

ObjectSpace.each_object(Class) is returning an Enumerator of Class 
object. Then you are shoving a bunch of class objects into an array and 
then expecting grep to know what to do with them.

If you were to run:

irb(main):> ObjectSpace.each_object(Class) { |x| p x.class }
Class
Class
Class
...
...
...
=> 383

Calling to_a on that Enumerator you get an array of Class objects, NOT 
strings. When sending the grep message to an Array return any elements 
where Pattern === element.

What you probably want instead is an array of class names as strings not 
Class objects. Then grep should work just fine.

You don't need libxslt, which is lucky as it does not exist.  Repeat
the apt-get but leave out libxslt.

If using rvm you must /not/ use sudo when installing gems.  However
you should not need to install it manually, just put it in Gemfile for
the application and bundle install will automatically install it.  You
do need sudo for installing the libxml stuff of course.

As I installed Ruby using RVM, I thought I need to install everything

What exactly do you mean by "Library". There are several of those on OS 
X.

/System/Library
System owned library. Definitely DO NOT delete, or otherwise touch 
anything here.

/Library
Global library for third-party application use, not user specific. 
Slightly less dangerous to mess with this stuff, but you shouldn't have 
to.

~/Library
This is you're library where you're user specific Preferences, 
Application Support, Caches, etc. are kept. You're free to do whatever 
you wish with this stuff.

With that out of the way I'll see if I can flesh this out a bit more...

Whether you choose RVM or rbenv, both (by default) create a hidden 
directory that is maintained by those tools. The tools are designed to 
be as unobtrusive to the normal operation of the operating system as 
possible (rbenv even more so than RVM).

You should see something like this:

$ cd ~
$ ls -la

-rw-r--r--@  1 robertwalker  staff  15364 Jan 14 16:42 .DS_Store
drwx--   3 robertwalker  staff102 Apr  5  2011 .MacOSX
drwxrwxrwt@  3 robertwalker  staff102 Apr 13  2011 .TemporaryItems
drwx--   2 robertwalker  staff 68 Jan 17 09:14 .Trash
...
drwxr-xr-x   5 robertwalker  staff170 Jul 19 13:56 .rbenv

If you notice that .rbenv (or .rvm) have a user other than yourself 
(e.g. root) your can fix that with:

$ chown -R robertwalker:staff .rbenv

Changes ownership of .rbenv and all it's contents recursively to user 
"robertwalker" and group "staff".

You must also make sure your PATH is configured properly for rbenv or 
RVM to work properly.

$ echo $PATH

/Users/robertwalker/.rbenv/shims:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin

Notice here that /Users/robertwalker/.rbenv/shims is the first path in 
the PATH environment variable. In the case of rbenv this is added by 
inserting this line...

# Enable rbenv shims and autocompletion
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

somewhere in your .profile (or similar) file. RVM has a similar setup. 
Read their docs for more.

Once you verify these things make sure to tell rbenv (or RVM) which 
version of your installed Rubies to use:

$ rbenv global 1.9.3-p327

That should be all that's necessary to get going with rbenv or RVM. I 
would recommend against messing with your system's built-in Ruby, or 
anything inside /System/Library or /Library.

Re: [Rails] Re: Need help even generating a new app

[Johnneylee Rollins]

Hey,

This is because you installed rvm, which is my preference but I have no
qualms about you using rbenv. For some reason the permissions on something
in your rvm directory got changed.

sudo chown -r $USER:/$USER $HOME/.rvm

That will help there. I can help you continue to use rvm if you want. If
~/.rvm/scripts/rvm is sourced in your shell, you likely just need to set a
new default ruby.

rvm list # lists locally installed rubies

You might want to make sure you have the one you want. I suggest rvm
install 1.9.3, which gets you the latest patch set rvm knows about.

After that, you do this

rvm use  --default

Whichever system you use, for simplicity, I'd suggest removing the other.

Oh! And, don't forget to set the newly installed Ruby as your default 
Ruby version:

$ rbenv global 1.9.3-p237

or

$ rbenv local 1.9.3-p237 (from inside your Rails project folder)

I see from those paths that you appear to be on a Mac. Here are my 
recommendations for getting started with the latest versions of Ruby and 
Rails.

Step 1: Install Homebrew.

http://mxcl.github.com/homebrew/

Step 2: Install and configure rbenv and ruby-build using Homebrew.

$ brew install rbenv
$ brew install ruby-build

https://github.com/sstephenson/rbenv

Step 3: Install Ruby 1.9.3

$ rbenv install 1.9.3-p327

Step 4: Install Rails

$ gem install rails

Step 5: Create a new Rails app:

$ rails new my_first_app

Step 6: Profit!

Yes, I know but currently I am looking forward to integrate Red5 server
because I hope without some media servers, the application will not handle
heavy traffic. I will look into HTML 5 once I get this done.

You could use a HTML5 solution with a Flash fallback, to be more future-ready.

If you're using the default amazon linux image, you won't be able to
scp in as root - root has remote access disabled. You need to sep in
using whatever user/credentials you used in 1. That article looks a
little out of date. If you're using the aforementioned linux image
(it's the default) then most of what it describes is already setup for
you. Lastly this isn't really anything to do with rails - there are
probably more suitable areas for discussing this (e.g. the official
aws forum, which has a bunch of amazon employees contributing)

Checkout the wepay-rails gem:

It handles the Oauth and IPN calls for you.

Thanks Colin and Fred,it works with<%= comment.commenter.name if

I still don't understand why some of the commenters are nil, but I
will take your advise and learn how to debug myself.
Thanks very much!!

As I asked previously, don't top post.  Thanks.

I think you must be mistaken, it cannot both be nil and User at the
same time.  As fred suggested, maybe some are ok and others are nil.
Try using something like
<%= comment.commenter.name if comment.commenter %>
Also have a look at the Rails Guide on debugging.  It will show you
how to use ruby-debug to break into your code and inspect data and
follow flow.

[Jeweller]

Well, I think Fred may be right. The path to my app contains some
Chinese, like "桌面". So I removed it to another directory, but there
came with a new error "undefined method `name' for nil:NilClass"
instead of the old one.

comment.commenter is a nilclass !!!but <%= comment.commenter %> it
got #

here is the model,there may be some problem.

class User < ActiveRecord::Base
  has_many :comments, :dependent => :destory
  #...
end

class Comment < ActiveRecord::Base
  belongs_to :commentable, :polymorphic => true
  belongs_to :micropost
  belongs_to :commenter, :class_name => "User", :foreign_key =>
"commenter_id"
  has_many :comments, :as => :commentable, :dependent => :destroy
# A comment can also be commented

I think Frederick is suggesting that there may be some unusual
characters in the path to your app that is causing the unusual error
messages.  What is the path to the app (something like
/home/jeweller/myapp for example)?

If there are such characters then the easy test to see if this is the
problem is to copy the entire app to a different location and run it
there (or just rename folders to ascii text).

Sorry, I don't know how to test it. I'm new to Rails. Could you
specify it?
Or let's say if you want a user able to comment on microposts and also
comments, what would you do?
I just don't want to use "act_as_commentable" gem, because I'm trying

I don't think it's related to the actual problem in your app but I do
think it could be triggering a bug in the backtrace cleaner stuff in
rails, which is obscuring the actual error you get. Should be easy
enough to test this hypothesis

[Rails] Re: need help with an awkard error

[Jeweller]

thanks ,Fred.
 I still don't understand,because in the model I use the
"validates_presense_of :commenter" to make sure the commenter
won't be nil.
Here's the file I used to generate sample data.

require 'faker'
def make_comments
  Micropost.all.each do |micropost|
User.all(:limit => 2).each do |user|
  micropost.comments.create!(:content =>
Faker::Lorem.sentence(4), :commenter => user)
end
  end
end

Now, every micropost has two comments, and the commenters are the
first,and the second one in the database.

In your opinon, what may brings to the situation ---" the path to your
rails app contain some non ASCII characters"

Well the main difference is that this is only displaying a single
name. If for example there is a comment where comment.commenter is nil
then calling .name on it would raise an error but your second example
would be ok unless the bad comment happens to be the first comment of
the first item.

I think the actual error message you get is something unrelated
happening during the process of preparing the error page. Does the
path to your rails app contain some non ASCII characters perhaps?

activerecord-oracle-adapter's last official version of Rails it worked with
was Rails 2 (2.1 if I recall correctly). It was replaced years ago
by activerecord-oracle_enhanced-adapter which works with Rails 2.3.* and
Rails 3. If you wish to use the older adapter you are going to have to use
an earlier version of Rails 2. I would suggest you tell your host to get
with the times and install activerecord-oracle_enhanced-adapter. If they
refuse then you are stuck with having to use an older version of Rails 2. At
that point I would seriously consider switching hosting providers.

I get confused sometimes too, but what helps me is to think about it
this way: if you are moving data to conform to a new schema, then it
is really part of the schema change and ergo belongs in a migration.
However, if you are changing data for some other purpose (for example
requiring everyone to reset their password on next login after some
security issue), then that would belong in something more of a rake/
capistrano task since its not schema related.

I believe when people saying migrations shouldn't change the records,
they mean outside of changes required by schema changes, which are
what the migrations are supposed to address.

My 2c,
\Peter

I do agree with you. But I read so many articles that state that the
migrations are supposed only to contain the structure of the tables, not
changes in the records.

I think I will stick with the migration then. It seems the best place to put
these scripts for now.

Why not a migration?  Seems like the correct place for a one-shot 
change.

Create the new table.
Migrate the data.
Once and done.

I've done this numerous times on a project as the design evolves (create 
new table(s), reorganize existing data), and the migrations provide the 
audit trail of the actions.

Just make sure your down action undoes everything appropriately, but 
that's what your dev environment is for, isn't it?

I think the suggestion is that line 5 of application.rb that has
init_gettex
on it, should be
init_gettext
In an earlier post you showed this line commented out (with #) but
presumably the error does not appear if it is commented out, likely a
different error appears.

I believe you say that the app is working on a different server, check
the line there to see what it is.  I trust you are picking the source
up from a source control system (git for example) in which case you
should be able to see whether you have accidentally modified that
line.  If the source is not in a version control system then get that
set up before you do anything and check into the VCS the version that
is running on the server.  Then check it out onto your system.  Do not
start editing it until you have got a VCS setup.  That is my advice
anyway.

Colin

Re: [Rails] Re: Need help on Dicom Image viewer

[radhames brito]

He had a path problem that was actually easy to solve and but he did convert
the image



""I have created a Rails application based on this tutorial:
http://dicom.rubyforge.org/tutorial1.html

I'm trying to view a DICOM image. I was able to convert .dcm to .jpg.

But, when I try to view the .jpg image I get as shown in the "Snapshot"
file attached within this message.

Where is the problem?

Thanks.

Why do you think you need a server-side viewer?  What have you found so 
far, and why do you think they won't work with Rails?

If you need a special viewer, it's probably implemented in client-side 
Java or JavaScript.  Neither of those care in the slightest about Rails; 
it's just a matter of furnishing them with the right image data.

I'm about 90% certain that you're trying to solve this problem wrong.

[Rails] Re: Need help on Dicom Image viewer

[A Sarkar]

DICOM is the image output of  an X-ray machine. X ray plates are
things of past. Radiologists all over the world use DICOM images to
read an X-ray. They have special monitor through which they can view
the DICOM image. But the problem is that we cannot find a server
version of DICOM image viewer that works on ROR platform.

Twitter & facebook both have apis that allow you to get at the user's
streams. You don't send their password though - a mechanism called
OAuth is used to get you a token that allows facebook etc to know that
the user has granted your application permission to access the user's
data (with various levels of granularity)

Most certainly you can.  I think maybe you would benefit from reading
the rails guides at http://guides.rubyonrails.org/v2.3.8/ Those will
be ok for 2.3.5 (why are you not using the latest 2.3 I wonder?).
Particularly Getting Started, ActiveRecord Associations, Routing, and
Debugging.

Colin, thanks so much for all your input.  As you can see, I'm just 
muddling my way through all this, and all of your comments are very 
helpful.  I will go through them more when I get to the office...

"remaining seats" = schedule.capacity - number of approved requests. 
So, if a schedule has a capacity of 10, and 8 requests with state_id = 3 
(approved), then there are 2 available slots before the capacity reaches 
0 and no more requests can be accepted.

Can I do request.schedule as a find in 2.3.5 or is that a 3.0 feature?

I used nitems because I didn't know any better.  :)

You've got me pointed in the right direction now - I'm new and messy, 
but I'm diggin it, so will keep pluggin away.

Thanks again!

[Rails] Re: need help installing Rails 3 on non-Intel Mac

[AppleII717]

"MacPorts is the Devil" 

About a month ago I succeeded in getting rails3 working on a G4
MacMini after upgrading to 10.5.8 from 10.4.?.

There where problems and most of them revolved around MacPorts. I
installed rubygems using MacPorts and dependencies would start looking
for stuff in /usr/local and blow up. I finally just took /opt/local
out of the picture and used /library/ruby for gems and /usr/local for
all other stuff (compile from source on installer using with something
using /usr/local).

While not as bad, I also had problems with RVM - but it might have
just been my usage. The G4 is more or less my productions server and
was running a couple applications I moveed from 2.x (actually one from
1.x) to rails3beta4.

I'll agree with "maddox", MacPorts is the Devil.
