When someone wants to add their favorite, check the database to see if
it exists. What's the problem?

I am assuming you know how to make a AJAX call. The above will explain
how to set an interval to call your function periodically.

Sure, it's very much possible. However, you need to post exactly what steps you've taken, and where exactly you're facing the problem, in order for the community to help you in any way :)

I just said what you need. chain the url_for method to add session id to the parameters, and read the session id in your application controller, look it up in your session store, active record or memcache, then load whatever information you want from the database.

Please suggest which route to follow, in order to make application work
even though cookies are disabled in the browser.

It's not secure, session spoofing is a serious issue. I would encourage not going that route.

It can be done in rails, needs a bit of work but sure. Ideally, you'll alias_method_chain url_for and read the session in a parent controller, like ApplicationController and initialize your current user and any other session information from that.

You cannot use sessions without cookies enabled.

That said, you might remember what PHP does with the PHPSESSIONID parameter appended to all URLs rendered in the page. You might want to do something similar.

Thanks Rajarshi for your reply!
But that's not my question is - let me put in other way:
If I am using sessionstore, the _session_id has to be passed through
browser cookie. Now, If I disable cookie in the browser the entire
system doesn't work. So, what is the other alternative I can pass the
session id through? if cookie is disabled.
Tried passing as request parameter, but that doesn't work. Any
suggestion plese?

Re: [Rails] How do I send session id other than from cookie.

Session is like an hash to store data with an application request.

It should work if you store a session while login like session[:user]="Myname_123"
it will renmain in the application until or unless you make it nil
session[:user]=nil

it is versy simple in consept

now session id it is identification of an particular session

and browser you know I use session in android emulator

now your turn

This way I will return a session id from login request and use the same

request.

Will this work?

[Rails] Help with has_many through association

I just posted a question on stackoverflow:

http://stackoverflow.com/questions/14096008/has-many-through-but-with-unique-source-and-multiple-associations

The gist of what I need help with is this:

As a user, I can add my favorite book to my book list.
Another user adds the same book to their book list.
There should only be one instance of the book in the database but 2 user/book associations.

Any help would be amazing!

[Rails] Re: CSRF tokens for mobile apps

I have an existing rails backend website which makes json ajax calls to my server and I was passing csrf tokens in every ajax call. Now,I am developing a mobile iOS app to use the same backend and send calls in json. However, mobile requests are failing with "Can't verify CSRF token authenticity", because i dont know of anyway to send the csrf token to rails from app.
Looking around, many people are suggesting to disable CSRF protection if the call is json call - but I dont want to do that because my website all uses json calls and that leaves my site open for attacks.
My question is:
1) How can i let my iOS app know the rails generated csrf token to use it in all app calls to server? Is it possible
2) Is there any other way that I can work around this problem?

Since this thread has been revived, it seems reasonable to mention that you may not want to use session state in your API at all - some HTTP clients may not support it out-of-the-box, etc. Oauth or Oauth2 is a possible alternative - there are some very slick gems to help with this (devise_oauth2_providable, among others).

Originally I had to get homebrew and

brew install libksba

but I did that already and it works. That leads to "Xcode and gcc:" and everything below it.

So, I have homebrew, and the following three commands work:

  brew update    brew tap homebrew/dupes    brew install autoconf automake apple-gcc42

But when I try

rvm pkg install openssl

this is what happens

Fetching openssl-1.0.1c.tar.gz to /Users/adamzerner/.rvm/archives  Extracting openssl to /Users/adamzerner/.rvm/src/openssl-1.0.1c  Configuring openssl in /Users/adamzerner/.rvm/src/openssl-1.0.1c.

And this is what happens when I try what it says...

Adam-Zerners-MacBook-Pro:~ adamzerner$ rvm reinstall all --force  Adam-Zerners-MacBook-Pro:~ adamzerner$

some other information...

I don't see a .rvm folder under adamzerner, so I can't read what it tells me to (not that I would understand what I'd be reading anyway).

It seems that I have 1.8.7 installed:

Adam-Zerners-MacBook-Pro:~ adamzerner$ ruby -v  ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]

So... to summarize... when I try to run

rvm install 1.9.3

I get the gcc/Xcode problem. To fix that it says to download apple-gcc42 from Homebrew. When I do that, I get a problem after doing

rvm pkg install openssl

The problem being that I need to reinstall all rubies. When I do that:

rvm reinstall all --force

it seems that nothing happens.

Thanks in advance to anyone willing to help me with this problem!

[Rails] no metadata found in activereocrd-3.2.9.gem when running bundle install in a rails 3.2.9

m a newbie in rails. working on Windows 7, 64 bits. Installed my environment through RailsInstaller. latest version ofcourse. When creating a new project, (keeping the gem file as default) and having the bundle install run, am getting the error

gem::package::FormatError: no metadata found in   D:/RailsInstaller/Ruby1.9.3/bin/cashe/activereocrd-3.2.9.gem  and error occurrend while installing activerecord (3.2.9), and bubndler cannot continue.  Make sure that gem install activerecord -v '3.2.9' succeeds before building.

I tried to run the gem install activerecord..as instructed still bundle install does not work and i cannot run the rails server. (rails s)

When changing the rails version in the app gem file to 3.2.8 instead of 3.2.9 everything seems to work and the rails server runs succefully. What is wrong?

[Rails] Searching database in Rails with multiple optional parameters

I have a Rails app with following schema:

User (id, username, user_type, master_id) Item ( id,itemname,master_id) Repairs (id, in_date, out_date, user_id, item_id)

The app is small so I have tried keeping db as simple as possible. A user can be Admin, Dealer or Manager. A manager can have many dealers under him(Both stored in same user table).

An Item can be a 'master item' like a computer(with many sub items like keyboard,mouse) or it can be just a small sub item. So a master item can have many sub items under it.

A repair is Repair history for item. A repair has an item and user associated with it.

I have a search for with following parameters ( ALl optional)

Manager Name
Dealer Name
Master Item
Sub Item
In date
Out date

If no 'Dealer Name' is specified I want results to have all Dealers under the specified 'manager name' included in results, if no 'Sub Item' is specified I want all items under 'Master Item' to be in the results.

How should the search controller be defined so as to keep code simple and maintainable? I dont really want to do an 'if' for each condition.

[Rails] Re: CSRF tokens for mobile apps

that is straight forward: just copy the form_authenticity_token to a header field and let your app send it back as header

https://github.com/mkristian/ixtlan-translations/blob/master/app/controllers/local_controller.rb

that is the controller I use as base for my controllers talking to rest-clients (GWT applications)

[Rails] Re: CSRF tokens for mobile apps

Hey Jim, don't be a jerk, especially when your answer is wrong.

Using <%= form_authenticity_token %> doesn't work because you don't have
a server to dynamically insert content into html as an app is static and
packaged on the client device (iPhone/iPad).

CSRF should not be a possible attack inside of an app. Your session is
isolated to the app and cross domain origin policies in the browser will
prevent the attack. Also, since you are using an app you can implement
sessions without the use of cookies entirely.

Re: [Rails] installing ruby 1.9.3 in michael hartl's ruby on rails tutorial

The compiler that comes with Xcode doesn't work with ruby.

You need to install the version of gcc that works with it and set up a symlink.

I'm on a plane so I don't have the details with me. Google a bit and you should find blog entries with details.

Adam-Zerners-MacBook-Pro:~ adamzerner$ rvm reinstall all --force  Adam-Zerners-MacBook-Pro:~ adamzerner$   
some other information...
I don't see a .rvm folder under adamzerner, so I can't read what it tells me to (not that I would understand what I'd be reading anyway).
It seems that I have 1.8.7 installed:
Adam-Zerners-MacBook-Pro:~ adamzerner$ ruby -v  ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]  
So... to summarize... when I try to run
rvm install 1.9.3  
I get the gcc/Xcode problem. To fix that it says to download apple-gcc42 from Homebrew. When I do that, I get a problem after doing
rvm pkg install openssl  
The problem being that I need to reinstall all rubies. When I do that:
rvm reinstall all --force  
it seems that nothing happens.
Thanks in advance to anyone willing to help me with this problem!
EDIT: I forgot to say this before. For the "long thing" up above, when I press q to continue, this is what happens...

what happens when you sudo ln -s /usr/bin/llvm-gcc-4.2 /usr/bin/gcc and re run the ruby install? – Oliver Atkinson Dec 25 at 10:35 Does the solution is this StackOverflow thread work for you? – Paul Fioravanti Dec 25 at 11:35 @OliverAtkinson is that all in one line? and should i type "usr" or "adamzerner"? – Adam Zerner Dec 25 at 17:36 @Paul Floravanti I'm not sure. I don't understand what's going on there enough, and I'm following a somewhat rigid rails tutorial and I'm not sure if doing something it says there will negate/interfere with anything I've done or will be doing in the tutorial. – Adam Zerner Dec 25 at 17:40 1 @AdamZerner copy and paste exactly what I put - and yes its /usr/ – Oliver Atkinson 2 days ago @OliverAtkinson when I copy and paste what you put and then re run the ruby install, the same "long thing" comes up – Adam Zerner 2 days ago
