  • Using redirect_to to :create action

    - by ajmurmann
    I am trying to redirect to the create method of another controller. However, I can't find a way to set the method to POST. This results in the index method to be called. Using :method => :post just creates a new parameter, but doesn't change the http method. Any ideas how to redirect to the create method?

It leaves me scratching my head..

  • is_admin? function in rails? - undefined method Error

    - by Newbie
    Hello! At the moment, I am creating some kind of admin panel/backend for my site. I want to do the following: Only admins (a user has a user_role(integer) -- 1 = admin, 2 = moderator, 3 = user) can see and access a link for the admin panel. So I created an admin_controller. In my admin controller I created a new function called is_admin?: class AdminController < ApplicationController def admin_panel end def is_admin? current_user.user_role == 1 end end my route looks like. map.admin_panel '/admin-panel', :controller => 'admin', :action => 'admin_panel' and in my _sidebar.html.erb (partial in applicaton.html.erb) I created the link: <%= link_to "Admin Panel", :admin_panel unless is_admin? %> Now I get an error called: undefined method `is_admin?' Where is the problem? Please help me solving this problem!

  • Using group_by with fields_for and accepts_nested_attributes_for

    - by Derek
    I have a the following rails models: class Release < ActiveRecord::Base has_many :release_questionnaires, :dependent => :destroy accepts_nested_attributes_for :release_questionnaires ... end class class ReleaseQuestionnaire < ActiveRecord::Base belongs_to :release belongs_to :milestone ... end class In my view code, I have the following form. <% form_for @release, ... do |f| %> ... <table class="questionnaires"> <% f.fields_for :release_questionnaires, @release.release_questionnaires.sort_by{|ra| ra.questionnaire.name} do |builder| %> ... <% end %> </table> <% end %> This works and allows me to view and edit the questionnaires as desired. However, I have an additional requirement to break the questionnaires out into their own tables grouped by the milestone they are associated to, rather than in a single table. It appears as though the group_by method is design to accomplish this, but I cannot get it to work as desired inside the tag. It may be that I'm missing something obvious, as I am a beginner... Any help is appreciated.

  • Pre-packaged Rails applications

    - by Craig
    Seems like most Rails applications have similar 'base' functionality. As such, it seems that there would be value in having pre-build Rails applications at various functionality points such as: basic User model with authentication using Authlogic #1 + openid integration #2 + authorization using declarative_authorization #3 + Administration module #4 + a Profile model Themes (useful stylesheets and such) Friendship model Geocoding ... In addition to the basic MVC stuff, these applications would include: testing harnesses seed data git support One could choose start from any of these functionality points. Other than the sample application that are available with the various gems/plugins, are there projects such as these? If not, I would certainly be willing to contribute what I have.

  • rails 3, active record: any way to tell how many unique values match a "x LIKE ?" query

    - by jpwynn
    I have a query to find all the phone numbers that match a partial expression such as "ends with 234" @matchingphones = Calls.find :all, :conditions => [ "(thephonenumber LIKE ?)", "%234"] The same phone number might be in the database several times, and so might be returned multiple times by this query if it matches. What I need is to know is UNIQUE phone numbers the query returns. For example if the database contains 000-111-1234 * 000-111-3333 000-111-2234 * 000-111-1234 * 000-111-4444 the existing query will return the 3 records marked with * (eg returns one phone number -1234 twice since it's in the database twice) what I need is a query that returns just once instance of each match, in this case 000-111-1234 * 000-111-2234 *

  • what is the right 'rails' way to add a link_to a new custom method

    - by jpwynn
    We're adding a new method 'delete_stuff' to the WidgetsController of a scaffolded app. in routes we added match 'widget/delete_stuff/:id' = 'widgets#delete_stuff' I CAN manually create html (GET) links like <a href="/widget/delete_stuff/<% widget.id %>">My Custom Delete Stuff</a> But that's bad on so many levels (uses GET instead of DELETE, doesn't permit a CONFIRM dialog, isnt DRY, etc) Problem is I can't figure out how to use the url helpers for a custom method... trying to do something like this: <% link_to 'DeleteStuff', @widget, :confirm => 'Are you sure?', :method => :delete %> But that just gets ignored when the html is rendered. I'm clearly missing something fundamental on how to use link_to, any help will be appreciated! Cheers, JP

  • Java method introspection from JRuby

    - by Colin Curtin
    Is there a way from JRuby to introspect on a Java object and find out its Java-land methods? Like what http://github.com/oggy/looksee provides, but for Java. Or like (someobject).methods - 1.methods This would be nice for just taking a look at what a Java object provides versus the APIDoc for it.

  • Commenting out protect_from_forgery

    - by Andy
    Hi, I was trying to use active record store but I kept getting an invalid authenticity token. Someone told me to remove my protect_from_forgery from application controller. I know that this would remove all auth tokens but I'm not sure if this is a good idea. Does active record store not need auth tokens? By the way, all I need is a way to dynamically calculate the number of users online and their session variables. If there is a better way than using active record store it would be nice to know.

  • Unable to read values from object returned from ActiveRecord.find

    - by Venki
    I make the following call to the DB. @patientRegistration = PatientRegistration.find(:all, :conditions=["name = '#{patientName}'"]) Search for patient registration based on a given name. I get a valid @patientRegistration object.When I invoke @patientRegistration.inspect it prints correctly all the values for the object in the DB. But when I try to read a particular attribute (Say id or name) by doing the following: @patientRegistration.id or @patientRegistration.name. I get invalid values. Either its blank or some junk values. I dont understand how inspect is able to retrieve all the values correctly but reading individual attributes gives invalid values. Thanks

  • How do I stop the scriptaculous blind-down effect from flickering when element has padding?

    - by ro
    Hi all, it seems that when the blind down effect is used on an element with padding it looks a bit awkward. It seems to blind down too far and then jumps back. It's a very subtle thing but is really annoying. I don't have an online example but if you go to the demo on github and give the element a padding-top or bottom with firebug or something you'll see what I mean. http://wiki.github.com/madrobby/scriptaculous/effect-blinddown Anybody found a way to stop it?

  • Rails select list reverts to top?

    - by Danny McClelland
    Hi Everyone, I have number of select lists in my rails application like this: <li>Company<span><%= f.select :company_id, Company.all.collect {|m| [m.companyname, m.id]} %></span></li> They all work well, except - sometimes if you go to the edit view, the select list reverts to the top item, not the item that was chosen when creating. So if you go to an edit view and then click update without actually making any changes, the lists default to the top item - even though you didn't touch them. Is there a way around this? Thanks, Danny

  • Best way to associate phone numbers with names

    - by Horace Loeb
    My application stores lots of its users friends' phone numbers. I'd like to allow users to associate names with these phone numbers, but I don't want to make users manually type in names (obviously). I'm curious what the best overall approach is here, as well as the best way to implement it Overall approach-wise, I imagine using Gmail / Yahoo / Windows Live contacts is best (the Facebook API doesn't let you access phone numbers), though the gems I've found for interacting with these contacts APIs (this and this) only give you access to the names and email addresses of each contact.

  • Rails - Preventing users from contributing to website when there score is too low - callback / obser

    - by adam
    A User can add a Sentence directly on my website, via twitter or email. To add a sentence they must have a minimum score. If they don't have the minimum score they cant post the sentence and a warning message is either flashed on the website, sent back to them via twitter or email. So I'm wondering how best to code this check. Im thinking a sentence observer. So far my thoughts are in before_create score_sufficient() - score ok = save - score too low = do not save In the case of too low i need to return some flag so that the calling code can then fire off teh relevant warning. What type of flag should I return? False is too ambiguous as that could refer to validation. I could raise an exception but that doesn't sound right or I could return a symbol? Is this even the right approach? What's the best way to code this?

  • Best Practices for a Web App Staging Server (on a budget)

    - by fig-gnuton
    I'd like to set up a staging server for a Rails app. I use git & github, Cap, and have a VPS with Apache/Passenger. I'm curious as to the best practices for a staging setup, as far as both the configuration of the staging server as well as the processes for interacting with it. I do know it should be as identical to the production server as possible, but restricting public access to it will limit that, so tips on securing it only for my use would also be great. Another specific question would be whether I could just create a virtual host on the VPS, so that the staging server could reside alongside the production one. I have a feeling there may be reasons to avoid this, though.

  • Mocha expects method

    - by Masha
    So my situation is: I have a 2 modules that have the same structure like that: module Module1 class Config def fee_rate 2 end end end So, say, Module2 would have class Config with the method fee_rate, just with a different value (those are actually implemented in a rails engine, but it shouldn't matter) and then my model can use either Module1 or Module2 to get the fee rate value like that: def config @config ||= "#{module_name.titleize}::Config".constantize.new @config end def get_value config.get_fee * some_other_value end What I'm trying to test is if get_fee function was called on the correct class: "#{model.module_name.titleize}::Config".constantize.any_instance.expects(:get_fee).at_least_once model.get_value and on the line when I call get_value I get the following error - undefined method `*' for nil:NilClass. I'm completely lost now, so I'd appreciate any help and ideas.

  • how to add a new value to a dropdown list in Rails

    - by LearnRails
    In my item table, I have a itemname column which is currently a dropdown list taking values from DB. <%= select 'item','itemname' , Item.find(:all).collect{|c| [c.itemname]},{:include_blank = 'Select Name'} How can I add a new value to this dropdown list through the application. Is there a provision to directly add value to the list? Thanks

  • Why would paperclip not assign an ID to my uploaded photos?

    - by Trip
    I just deployed to a cluster server, and my delayed_jobs recipe was overwritten in the process. I solved that, delayed_jobs is up and running but can't find the ID of images that are uploaded.

Anyone know where I could poke and pry from here? UPDATE: I created a clone application on a single server. And there are no problems. The images on the cluster do show up (occassionally). If I keep clicking on the folders that lead to photos, it will 50% of the time return a 404 with it not being able to find the photo, and the other half it will present the photo. So the problem has got to be with the server interaction between the ActiveRecord through multiple servers.

  • post-install hook for a particular gem

    - by Henry Flower
    Here is what I've googled: http://www.mail-archive.com/[email protected]/msg02168.html Gem.post_install do |installer| puts "!!! #{installer.spec.full_name} INSTALLED !!!" end But where to put this snipped? If I put it in my Rakefile and/or src_of_myproject/lib/rubygems_plugin.rb file, than build the gem, install it--but the expected string is never printed after the installation. I'm totally confused. How to embed the post-install hook into the gem spec? Update: it's getting more interesting. If I put Gem.post_uninstall hook in src_of_myproject/lib/rubygems_plugin.rb--that hook works. Gem.post_uninstall do |uninstaller| puts "!!! #{uninstaller.spec.full_name} UNINSTALLED !!!" end Hm... And wtf is with Gem.post_install?
