  • ID + Slug name in URL in Rails (like in StackOverflow)

    - by Vitaly
    Hey, I'm trying to achieve URLs like this in Rails: http://localhost/posts/1234/post-slug-name with both ID and slug name instead of either http://localhost/posts/1234 or http://localhost/posts/post-slug-name (right now I have just slug name in URL, so this part is over). How can I do this? UPD I found an article on this: http://augustl.heroku.com/blog/styling-rails-urls, instead of /id/slug it suggests to use /id-slug which works perfectly for me, so I'll go with this.

  • 'sript/console test' with spork and rspec not loading the whole environment?

    - by TheDeeno
    I'm trying to load up console to interact with some of my rspec mocking helpers. I expected that running script/console test would load an env similar to when I run spec. However, this doesn't appear to be the case. It looks like spec_helper is never loaded. Or, if it is, it's not actually running through the logic because spork has polluted it a bit. In short, is there a quick and easy way to get an interactive rspec party going?

  • adding model validation errors in rescue

    - by ash34
    I have the following model with a virtual attribute class Mytimeperiod < ActiveRecord::Base validates presence of :from_dt validates_format_of :from_dt, :with => /\A\d{2}\/\d{2}\/\d{4}\Z/, :message => "format is mm/dd/yyyy" def from_dt self.from_date.strftime("%m/%d/%Y") if !self.from_date.blank? end def from_dt=(from_dt) self.from_date = Date.parse(from_dt) rescue self.errors.add_to_base("invalid from dt") end end I am using <%= f.error_messages %> to display the error messages on the form. I am using from_dt as a virtual attribute (string). The 'presence of' and 'format of' validation errors show up on the form, but when the user enters an invalid date format on the form and Date.Parse raises an exception I have a 'errors.add_to_base' statement in the rescue clause. Can anyone tell me why this error does not show up in the form error messages when I disable the 'format of' validation. thanks.

  • Good way to handle inline-edit form using Rails and jQuery

    - by Tim Sullivan
    I have a list of items, being displayed in a series of DIVs. When someone clicks on an "edit" link, I want to replace the div with a form that will let them edit the contents of that item in a nice way. I'm trying to think of the ideal way to handle this. Do I create a hidden edit form for every item in the list, and hook the edit link to reveal it, like this: <div> <a href="#">edit</a> Item One <div id="edit_1202" class="editform">Edit form goes here</div> </div> <div> <a href="#">edit</a> Item Two <div id="edit_2318" class="editform">Edit form goes here</div> </div> Or is there a better way to fetch the data and insert the form's HTML into the right spot? Remember, I'm using jQuery, so I can't use the prototype helpers. Thanks!

  • Updating extra attributes in a has_many, :through relationship using Rails

    - by Robbie
    I've managed to set up a many-to-many relationship between the following models Characters Skills PlayerSkills PlayerSkills, right now, has an attribute that Skills don't normally have: a level. The models look something like this (edited for conciseness): class PlayerSkill < ActiveRecord::Base belongs_to :character belongs_to :skill end class Skill < ActiveRecord::Base has_many :player_skills has_many :characters, :through => :player_skills attr_accessible :name, :description end class Character < ActiveRecord::Base belongs_to :user has_many :player_skills has_many :skills, :through => :player_skills end So nothing too fancy in the models... The controller is also very basic at this point... it's pretty much a stock update action. The form I'm looking to modify is characters#edit. Right now it renders a series of checkboxes which add/remove skills from the characters. This is great, but the whole point of using has_many :through was to track a "level" as well. Here is what I have so far: - form_for @character do |f| = f.error_messages %p = f.label :name %br = f.text_field :name %p = f.label :race %br = f.text_field :race %p = f.label :char_class %br = f.text_field :char_class %p - @skills.each do |skill| = check_box_tag "character[skill_ids][]", skill.id, @character.skills.include?(skill) =h skill.name %br %p = f.submit After it renders "skill.name", I need it to print a text_field that updates player_skill. The problem, of course, is that player_skill may or may not exist! (Depending on if the box was already ticked when you loaded the form!) From everything I've read, has_many :through is great because it allows you to treat the relationship itself as an entity... but I'm completely at a loss as to how to handle the entity in this form. As always, thanks in advance for any and all help you can give me!

  • Rails ActiveResource Associations

    - by brad
    I have some ARes models (see below) that I'm trying to use associations with (which seems to be wholly undocumented and maybe not possible but I thought I'd give it a try) So on my service side, my ActiveRecord object will render something like render :xml => @group.to_xml(:include => :customers) (see generated xml below) The models Group and Customers are HABTM On my ARes side, I'm hoping that it can see the <customers> xml attribute and automatically populate the .customers attribute of that Group object , but the has_many etc methods aren't supported (at least as far as I can tell) So I'm wondering how ARes does it's reflection on the XML to set the attributes of an object. In AR for instance I could create a def customers=(customer_array) and set it myself, but this doesn't seem to work in ARes. One suggestion I found for an "association" is the just have a method def customers Customer.find(:all, :conditions => {:group_id => self.id}) end But this has the disadvantage that it makes a second service call to look up those customers... not cool I'd like my ActiveResource model to see that the customers attribute in the XML and automatically populate my model. Anyone have any experience with this?? # My Services class Customer < ActiveRecord::Base has_and_belongs_to_many :groups end class Group < ActiveRecord::Base has_and_belongs_to_many :customer end # My ActiveResource accessors class Customer < ActiveResource::Base; end class Group < ActiveResource::Base; end # XML from /groups/:id?customers=true <group> <domain>some.domain.com</domain> <id type="integer">266</id> <name>Some Name</name> <customers type="array"> <customer> <active type="boolean">true</active> <id type="integer">1</id> <name>Some Name</name> </customer> <customer> <active type="boolean" nil="true"></active> <id type="integer">306</id> <name>Some Other Name</name> </customer> </customers> </group>

  • Sqs vs SqsGen2 using RightScale right_aws GEM

    - by Fitter Man
    I'm trying to use the right_aws (1.10.0) GEM with Rails, and I've reduced my problem to a 3-line irb session. The following works require 'rubygems' require 'right_aws' sqs = RightAws::Sqs.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") while this fails require 'rubygems' require 'right_aws' sqs = RightAws::SqsGen2.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") with NameError: uninitialized constant RightAws::SqsGen2. I see the class definition in the GEM source, the documentation is old but seems accurate, but I can't figure out what I'm doing wrong. And while you're at it, is there any reason if I'm building something new, I'd want to use the older interface?

  • Validation not bubbling up to my other models.

    - by DJTripleThreat
    Ok, I have a relationship between People, Users and Employees such that All Employees are Users and all Users are People. Person is an abstract class that User is derived from and Employee is derived from that. Now... I have an EmployeesController class and the create method looks like this: def create @employee = Employee.new(params[:employee]) @employee.user = User.new(params[:user]) @employee.user.person = Person.new(params[:person]) respond_to do |format| if @employee.save flash[:notice] = 'Employee was successfully created.' format.html { redirect_to(@employee) } format.xml { render :xml => @employee, :status => :created, :location => @employee } else format.html { render :action => "new" } format.xml { render :xml => @employee.errors, :status => :unprocessable_entity } end end end As you can see, when I'm using the :polymorphic => true clause, the way you access the super class is by doing something like @derived_class_variable.super_class_variable.super_super_etc. The Person class has a validates_presence_of :first_name and when it is satisfied, on my form, everything is OK. However, if I leave out the first name, it won't prevent the employee from being saved. What happens is that the employee record is saved but the person record isn't (because of the validation). How can I get the validation errors to show up in the flash object?

  • Building an extension framework for a Rails app

    - by obvio171
    I'm starting research on what I'd need in order to build a user-level plugin system (like Wordpress plugins) for a Rails app, so I'd appreciate some general pointers/advice. By user-level plugin I mean a package a user can extract into a folder and have it show up on an admin interface, allowing them to add some extra configuration and then activate it. What is the best way to go about doing this? Is there any other opensource project that does this already? What does Rails itself already offer for programmer-level plugins that could be leveraged? Any Rails plugins that could help me with this? A plugin would have to be able to: run its own migrations (with this? it's undocumented) have access to my models (plugins already do) have entry points for adding content to views (can be done with content_for and yield) replace entire views or partials (how?) provide its own admin and user-facing views (how?) create its own routes (or maybe just announce its presence and let me create the routes for it, to avoid plugins stepping on each other's toes) Anything else I'm missing? Also, is there a way to limit which tables/actions the plugin has access to concerning migrations and models, and also limit their access to routes (maybe letting them include, but not remove routes)? P.S.: I'll try to keep this updated, compiling stuff I figure out and relevant answers so as to have a sort of guide for others.

  • optional local variables in rails partial templates: how do I get out of the (defined? foo) mess?

    - by brahn
    I've been a bad kid and used the following syntax in my partial templates to set default values for local variables if a value wasn't explicitly defined in the :locals hash when rendering the partial -- <% foo = default_value unless (defined? foo) %> This seemed to work fine until recently, when (for no reason I could discern) non-passed variables started behaving as if they had been defined to nil (rather than undefined). As has been pointed by various helpful people on SO, http://api.rubyonrails.org/classes/ActionView/Base.html says not to use defined? foo and instead to use local_assigns.has_key? :foo I'm trying to amend my ways, but that means changing a lot of templates. Can/should I just charge ahead and make this change in all the templates? Is there any trickiness I need to watch for? How diligently do I need to test each one?

  • Running a SQL query in rails

    - by Bharat
    Hello I have a rails application where I have to subtract 2 time stamps and display the result on the webpage I have used the following sql statement and I am getting the results. select (julianday(resolutions.created_at)-julianday(tickets.created_at))*24 from tickets,resolutions the value of tickets.created_at is 2010-04-05 18:59:02 which is a time stamp and value of resolutions.created_at is 2010-04-08 08:10:33 Now where do I put this sql so that I can be seen in my webpage. I tired it in the views page with the following but nothing showed up: <% @sql = "select (julianday(resolutions.created_at)-julianday(tickets.created_at))*24 from tickets,resolutions" %> <% @t=(ActiveRecord::Base.connection.execute(@sql)) %> So how do I display it on my webpage? when I perform the above I get the output printed on the webpage as 061.1919444389641(julianday(resolutions.created_at)-julianday(tickets.created_at))*2461.1919444389641 only 61.1919444389641 is supposed to be printed but the query statement is also getting printed.

  • ActionMailer execution timeout

    - by user275729
    When trying to send an email to the user for reseting their password, I keep getting an execution timed out error. Other mailer functions work, so I know that the config settings are correct. The header reads: "Timeout::Error in Password resetsController#create" Here is the password_resets_controller: def create @user = User.find_by_email(params[:email]) if @user User.deliver_password_reset_instructions(@user.id) flash[:notice] = "Instructions to reset your password have been emailed to you.

  • Rails fields_for parameters for a has_many relation don't yield an Array in params

    - by user1289061
    I have a model Sensor with has_many and accepts_nested_attributes_for relationships to another model Watch. In a form to update a Sensor, I have something like the following <%= sensor_form.fields_for :watches do |watches_form| %> <%= watches_form.label :label %><br /> <%= watches_form.text_field :label %> <% end %> This is indended to allow editting of the already-created Watches belonging to a Sensor. This call spits form inputs as so: <input name="sensor[watches_attributes][0][label]" ... /> <input name="sensor[watches_attributes][0][id]" ... /> When this gets submitted, the params object in the Sensor controller gets an assoc like "sensor" => { "id"=>"1", "watches_attributes"=> { "0"=>{"id" => "1", "label" => "foo"}, "1"=>{"id" => "2", "label" => "bar"} } } For a has_many, accepts_nested_attributes_for update to work upon the @sensor.update_attributes call, it seems that that attributes key really must map to an Array. From what I've seen in the examples, the combination of has_many, accepts_nested_attributes_for, and sensor_form.fields_for should allow me to pass the resulting params object directly to @sensor.update_attributes and update each related object as intended. Instead the Sensor takes place, with no errors, but the Watch objects are not updated (since "watches_attributes" maps to a Hash instead of an Array?) Have I missed something?

  • Should I stop redirecting after successful POST or PUT requests?

    - by Andres Jaan Tack
    It seems common in the Rails community, at least, to respond to successful POST, PUT or DELETE requests by redirecting instead of returning success. For instance, if I PUT a legal change to my user profile, the idiomatic response would be a 302 Redirect to the profile page. Isn't this wrong? Shouldn't we be returning 200 OK from the request? Or a 201 Created, in the case of a POST request? Either of those, in the HTTP/1.1 Status Definitions are allowed to (or required to) include a response, anyway. I guess I'm wondering, before I go and "fix" my application, whether there is there a darn good reason why the community has gone the way of redirects instead of successful responses.

  • How can I save an entire list of items true or false?

    - by JZ
    I'm following Ryan Bates, Railscast episode 52 and I've translated relevant parts of the code to work with Rails 3.0.0.beta2. In Ryan's case, he simply marks items incomplete and saves a timestamp. If an Item contains a timestamp the model returns the item in the completed list. I'm attempting to save ALL values true or false, depending on whether the check_box_tag is selected or not (using boolean). I am able to save ONLY selected items, true or false. How can I save an entire list of items true or false, depending on whether the checkbox is selected? The following is my attempt: controller logic: def yardsign Add.update_all(["yardsign=?", true], :id => params[:yard_ids]) redirect_to adds_path end html.erb: <%= form_tag yardsign_adds_path, :method => :put do %> <% @adds.each do |add| %> <td><%= check_box_tag "yard_ids[]", add.id %></td> <% end %> <% end %> routes.rb resources :adds do collection do put :yardsign end end Terminal Started POST "/adds/yardsign" for 127.0.0.1 at 2010-04-15 19:22:49 Processing by AddsController#yardsign as HTML Parameters: {"commit"=>"Update", "yardsigntakers"=>["1", "2"], "authenticity_token"=>"3arhsxg/Ky+0W7RNM2T3QditMTJmOnLR5CqmMYWN4Qw="} User Load (0.3ms) SELECT "users".* FROM "users" WHERE ("users"."id" = 1) LIMIT 1 SQL (1.8ms) UPDATE "adds" SET yardsign='t' WHERE ("adds"."id" IN (1, 2)) Redirected to http://localhost:3000/adds

  • 406 Not Acceptable error when using Jquery $.post in Firefox but not in Safari or Chrome

    - by jlfenaux
    I'm using Jquery (1.3.2) $.post command to trigger an ajax call to a rails server. The code works great on Safari and on Google Chrome (mac), but when I tried it on Firefox (3.5.7), I got a weird '406 Not Acceptable' error. When I look at the headers, it Firefox indicated that it accepted only ' text/javascript' responses. And the response Content-Type was 'text/html; charset=utf-8'. In Chrome the accepted types were 'application/json, text/javascript, /, text/javascript' and the response Content-Type was 'application/json; charset=utf-8'. I tried to force the content type in rails to 'text/javascript' format.json do render :json => @races.to_json, :content_type => 'text/javascript' end The content type is indeed changed in Chrome, but not in Firefox where it remains 'text/html'. Here is the code I used to trigger the ajax call. $.post( "/locator", params, function(data){...}, "json" ); Is there something I can do to make this work in Firefox? Thanks
