  • rails gem permissions problem (tabs on rails)

    - by aguynamedloren
    I'm having trouble running a gem, tabs on rails -v=1.3.2, in my rails 2.3.8 app. The gem is installed locally (Ubuntu 10.10) and I have config.gem "tabs_on_rails", :version="1.3.2" in environment.rb. This is the output I get when I run script/server: loren@ubuntu:~/apps/medmentum$ script/server => Booting WEBrick => Rails 2.3.8 application starting on http://0.0.0.0:3000 no such file to load -- tabs_on_rails /usr/lib/ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require' /usr/lib/ruby/1.8/rubygems/custom_require.rb:36:in `require' /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:156:in `require' /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:521:in `new_constants_in' /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:156:in `require' /var/lib/gems/1.8/gems/rails-2.3.8/lib/rails/gem_dependency.rb:215:in `load' /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:307:in `load_gems' /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:307:in `each' /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:307:in `load_gems' /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:164:in `process' /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:113:in `send' /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:113:in `run' /home/loren/apps/medmentum/config/environment.rb:11 /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:156:in `require' /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:521:in `new_constants_in' /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:156:in `require' /var/lib/gems/1.8/gems/rails-2.3.8/lib/commands/server.rb:84 /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' script/server:3 /var/lib/gems/1.8/gems/rails-2.3.8/lib/rails/plugin.rb:158:in `read': Permission denied - /var/lib/gems/1.8/gems/tabs_on_rails-1.3.2/rails/init.rb (Errno::EACCES) from /var/lib/gems/1.8/gems/rails-2.3.8/lib/rails/plugin.rb:158:in `evaluate_init_rb' from /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/core_ext/kernel/reporting.rb:11:in `silence_warnings' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/rails/plugin.rb:154:in `evaluate_init_rb' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/rails/plugin.rb:48:in `load' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/rails/plugin/loader.rb:38:in `load_plugins' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/rails/plugin/loader.rb:37:in `each' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/rails/plugin/loader.rb:37:in `load_plugins' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:369:in `load_plugins' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:165:in `process' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:113:in `send' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/initializer.rb:113:in `run' from /home/loren/apps/medmentum/config/environment.rb:11 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:156:in `require' from /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:521:in `new_constants_in' from /var/lib/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:156:in `require' from /var/lib/gems/1.8/gems/rails-2.3.8/lib/commands/server.rb:84 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from script/server:3 When I run rake gems:install, I get this: Permission denied - /var/lib/gems/1.8/gems/tabs_on_rails-1.3.2/rails/init.rb I navigated to the tabs_on_rails gem folder in the filesystem and all of the files are locked. According to the files' properties, I am not the owner and cannot change the permissions. All of my other local gems are accessible without permissions problems, so this is odd. Any help is very much appreciated!

  • Where is meta.local_fields set in django.db.models.base.py ?

    - by BryanWheelock
    I'm getting the error: Exception Value: (1110, "Column 'about' specified twice") As I was reviewing the Django error page, I noticed that the customizations the model User, seem to be appended to the List twice. This seems to be happening here in django/db/model/base.py in base_save(): values = [(f, f.get_db_prep_save(raw and getattr(self, f.attname) or f.pre_save(self, True))) for f in meta.local_fields] this is what Django error page shows values to be: values = [(<django.db.models.fields.CharField object at 0xa78996c>, u'kallie'), (<django.db.models.fields.CharField object at 0xa7899cc>, ''), (<django.db.models.fields.CharField object at 0xa789a2c>, ''), (<django.db.models.fields.EmailField object at 0xa789a8c>, u'[email protected]'), (<django.db.models.fields.CharField object at 0xa789b2c>, 'sha1$d4a80$0e5xxxxxxxxxxxxxxxxxxxxddadfb07'), (<django.db.models.fields.BooleanField object at 0xa789bcc>, False), (<django.db.models.fields.BooleanField object at 0xa789c6c>, True), (<django.db.models.fields.BooleanField object at 0xa789d2c>, False), (<django.db.models.fields.DateTimeField object at 0xa789dcc>, u'2010-02-03 14:54:35'), (<django.db.models.fields.DateTimeField object at 0xa789e2c>, u'2010-02-03 14:54:35'), # this is where the values from the User model customizations show up (<django.db.models.fields.BooleanField object at 0xa8c69ac>, False), (<django.db.models.fields.CharField object at 0xa8c688c>, None), (<django.db.models.fields.PositiveIntegerField object at 0xa8c69cc>, 1), (<django.db.models.fields.CharField object at 0xa8c69ec>, 'b5ab1603b2308xxxxxxxxxxx75bca1'), (<django.db.models.fields.SmallIntegerField object at 0xa8c6dac>, 0), (<django.db.models.fields.SmallIntegerField object at 0xa8c6e4c>, 0), (<django.db.models.fields.SmallIntegerField object at 0xa8c6e8c>, 0), (<django.db.models.fields.SmallIntegerField object at 0xa8c6ecc>, 10), (<django.db.models.fields.DateTimeField object at 0xa8c6eec>, u'2010-02-03 14:54:35'), (<django.db.models.fields.CharField object at 0xa8c6f2c>, ''), (<django.db.models.fields.URLField object at 0xa8c6f6c>, ''), (<django.db.models.fields.CharField object at 0xa8c6fac>, ''), (<django.db.models.fields.DateField object at 0xa8c6fec>, None), (<django.db.models.fields.TextField object at 0xa8cb04c>, ''), # at this point User model customizations repeats itself (<django.db.models.fields.BooleanField object at 0xa663b0c>, False), (<django.db.models.fields.CharField object at 0xaa1e94c>, None), (<django.db.models.fields.PositiveIntegerField object at 0xaa1e34c>, 1), (<django.db.models.fields.CharField object at 0xaa1e40c>, 'b5ab1603b2308050ebd62f49ca75bca1'), (<django.db.models.fields.SmallIntegerField object at 0xa8c6d8c>, 0), (<django.db.models.fields.SmallIntegerField object at 0xaa2378c>, 0), (<django.db.models.fields.SmallIntegerField object at 0xaa237ac>, 0), (<django.db.models.fields.SmallIntegerField object at 0xaa237ec>, 10), (<django.db.models.fields.DateTimeField object at 0xaa2380c>, u'2010-02-03 14:54:35'), (<django.db.models.fields.CharField object at 0xaa2384c>, ''), (<django.db.models.fields.URLField object at 0xaa2388c>, ''), (<django.db.models.fields.CharField object at 0xaa238cc>, ''), (<django.db.models.fields.DateField object at 0xaa2390c>, None), (<django.db.models.fields.TextField object at 0xaa2394c>, '')] Since this app is in Production, I can't figure out how to use pdb.set_trace() to see what's going on inside of save_base.

  • Ruby on Rails: url_for :back leads to NoMethodError for back_url

    - by Platinum Azure
    Hi all, I'm trying to use url_for(:back) to create a redirect leading back to a previous page upon a user's logging in. I've had it working successfully for when the user just goes to the login page on his or her own. However, when the user is redirected to the login page due to accessing a page requiring that the user be authenticated, the redirect sends the user back to the page before the one s/he had tried to access with insufficient permissions. I'm trying to modify my login controller action to deal with the redirect properly. My plan is to have a query string parameter "redirect" that is used when a forced redirect occurs. In the controller, if that parameter exists that URL is used; otherwise, url_for(:back) is used, or if that doesn't work (due to lack of HTTP_REFERER), then the user is redirected to the site's home page. Here is the code snippet which is supposed to implement this logic: if params[:redirect] @url = params[:redirect] else @url = url_for :back @url ||= url_for :controller => "home", :action => "index" end The error I get is: NoMethodError in UsersController#login undefined method `back_url' for # RAILS_ROOT: [obscured] Application Trace | Framework Trace | Full Trace

  • How to test Rails 3 Engines with Cucumber & Rspec?

    - by cowboycoded
    I apologize if this question is slightly subjective... I am trying to figure out the best way to test Rails 3 Engines with Cucumber & Rspec. In order to test the engine a rails 3 app is necessary. Here is what I am currently doing: Add a rails test app to the root of the gem (myengine) by running: rails new /myengine/rails_app Add Cucumber to /myengine/rails_app/features as you would in a normal Rails app Require the Rails Engine Gem (using :path=>"/myengine") in /myengine/rails_app/Gemfile Add spec to the root directory of the gem: /myengine/spec Include the fixtures in /myengine/spec/fixtures and I add the following to my cuc env.rb: env.rb: Fixtures.reset_cache fixtures_folder = File.join(Rails.root, 'spec', 'fixtures') fixtures = Dir[File.join(fixtures_folder, '*.yml')].map {|f| File.basename(f, '.yml') } Fixtures.create_fixtures(fixtures_folder, fixtures) Do you see any problems with setting it up like this? The tests run fine, but I am a bit hesitant to put the features inside the test rails app. I originally tried putting the features in the root of the gem and I created the test rails app inside features/support, but for some reason my engine would not initialize when I ran the tests, even though I could see the app loading everything else when cuc ran. If anyone is working with Rails Engines and is using cuc and rspec for testing, I would be interested to hear your setup.

  • How to force reload all vendor/plugins in rails 2.3 (development mode)

    - by tsdbrown
    We have an application with a app/model that references another model stored in a plugin. When the app/model level is reloaded on the second and further requests and that relies on our model in vendor/plugins/... (which stays loaded) it fails (can't dup nil class). We've tried setting config.reload_plugins = true in the development.rb but this doesn't seem to do it. Does anybody know a way to handle this?

  • Django models: Use multiple values as a key?

    - by Rosarch
    Here is a simple model: class TakingCourse(models.Model): course = models.ForeignKey(Course) term = models.ForeignKey(Term) Instead of Django creating a default primary key, I would like to use both course and term as the primary key - taken together, they uniquely identify a tuple. Is this allowed by Django? On a related note: I am trying to represent users taking courses in certain terms. Is there a better way to do this? class Course(models.Model): name = models.CharField(max_length=200) requiredFor = models.ManyToManyField(RequirementSubSet, blank=True) offeringSchool = models.ForeignKey(School) def __unicode__(self): return "%s at %s" % (self.name, self.offeringSchool) class MyUser(models.Model): user = models.ForeignKey(User, unique=True) takingReqSets = models.ManyToManyField(RequirementSet, blank=True) takingTerms = models.ManyToManyField(Term, blank=True) takingCourses = models.ManyToManyField(TakingCourse, blank=True) school = models.ForeignKey(School) class TakingCourse(models.Model): course = models.ForeignKey(Course) term = models.ForeignKey(Term) class Term(models.Model): school = models.ForeignKey(School) isPrimaryTerm = models.BooleanField()

  • Rails 2 support after Rails 3 has been released

    - by J. Pablo Fernández
    Is there some plan or estimate about how long will Rails 2 be supported after Rails 3 has been released? I wanted to ride the wave and move to Rails 3 right away, specially for projects that may take 4 or 6 months to finish (so that they would probably be released with Rails 3.0.0 final) but I've found many things still not working, many basic plugins and gems; so I believe I'm stuck with Rails 2 for now.

  • Populating Models from other Models in Django?

    - by JT
    This is somewhat related to the question posed in this question but I'm trying to do this with an abstract base class. For the purposes of this example lets use these models: class Comic(models.Model): name = models.CharField(max_length=20) desc = models.CharField(max_length=100) volume = models.IntegerField() ... <50 other things that make up a Comic> class Meta: abstract = True class InkedComic(Comic): lines = models.IntegerField() class ColoredComic(Comic): colored = models.BooleanField(default=False) In the view lets say we get a reference to an InkedComic id since the tracer, err I mean, inker is done drawing the lines and it's time to add color. Once the view has added all the color we want to save a ColoredComic to the db. Obviously we could do inked = InkedComic.object.get(pk=ink_id) colored = ColoredComic() colored.name = inked.name etc, etc. But really it'd be nice to do: colored = ColoredComic(inked_comic=inked) colored.colored = True colored.save() I tried to do class ColoredComic(Comic): colored = models.BooleanField(default=False) def __init__(self, inked_comic = False, *args, **kwargs): super(ColoredComic, self).__init__(*args, **kwargs) if inked_comic: self.__dict__.update(inked_comic.__dict__) self.__dict__.update({'id': None}) # Remove pk field value but it turns out the ColoredComic.objects.get(pk=1) call sticks the pk into the inked_comic keyword, which is obviously not intended. (and actually results in a int does not have a dict exception) My brain is fried at this point, am I missing something obvious, or is there a better way to do this?

  • How to extend an 'unloadable' Rails plugin?

    - by Vitaly Kushner
    I'm trying to write a plugin that will extend InheritedResources. Specifically I want to rewrite some default helpers. And I'd like it to "just work" once installed, w/o any changes to application code. The functionality is provided in a module which needs to be included in a right place. The question is where? :) The first attempt was to do it in my plugin's init.rb: InheritedResources::Base.send :include, MyModule It works in production, but fails miserably in development since InheritedResource::Base declared as unloadable and so its code is reloaded on each request. So my module is there for the first request, and then its gone. InheritedResource::Base is 'pulled' in again by any controller that uses it: Class SomeController < InheritedResource::Base But no code is 'pulling in' my extension module since it is not referenced anywhere except init.rb which is not re-loaded on each request So right now I'm just including the module manually in every controller that needs it which sucks. I can't even include it once in ApplicationController because InheritedResources inherites from it and so it will override any changes back. update I'm not looking for advice on how to 'monkey patch'. The extension is working in production just great. my problem is how to catch moment exactly after InheritedResources loaded to stick my extension into it :) update2 another attempt at clarification: the sequence of events is a) rails loads plugins. my plugin loads after inherited_resources and patches it. b) a development mode request is served and works c) rails unloads all the 'unloadable' code which includes all application code and also inherited_resources d) another request comes in e) rails loads controller, which inherites from inherited resources f) rails loads inherited resources which inherit from application_controller g) rails loads application_contrller (or may be its already loaded at this stage, not sure) g) request fails as no-one loaded my plugin to patch inherited_resources. plugin init.rb files are not reloaded I need to catch the point in time between g and h

  • Show models.ManyToManyField as inline, with the same form as models.ForeignKey inline

    - by Kristian
    I have a model similar to the following (simplified): models.py class Sample(models.Model): name=models.CharField(max_length=200) class Action(models.Model): samples=models.ManyToManyField(Sample) title=models.CharField(max_length=200) description=models.TextField() Now, if Action.samples would have been a ForeignKey instead of a ManyToManyField, when I display Action as a TabularInline in Sample in the Django Admin, I would get a number of rows, each containing a nice form to edit or add another Action. However; when I display the above as an inline using the following: class ActionInline(admin.TabularInline): model=Action.samples.through I get a select box listing all available actions, and not a nifty form to create a new Action. My question is really: How do I display the ManyToMany relation as an inline with a form to input information as described? In principle it should be possible since, from the Sample's point of view, the situation is identical in both cases; Each Sample has a list of Actions regardless if the relation is a ForeignKey or a ManyToManyRelation. Also; Through the Sample admin page, I never want to choose from existing Actions, only create new or edit old ones.

  • Writing tests for Rails plugins

    - by Adam
    I'm working on a plugin for Rails that would add limited in-memory caching to ActiveRecord's finders. The functionality itself is mature enough, but I can't for the life of me get unit tests to work with the plugin. I now have under vendor/plugins/my_plugin/test/my_plugin_test.rb a standard subclass of ActiveSupport::TestCase with a couple of basic tests. I try running 'rake test' from the plugin directory, and I have confirmed that this task loads the ruby file with the test case, but it doesn't actually run any of the tests. I followed the Rails plugin guide (http://guides.rubyonrails.org/plugins.html) where applicable, but it seems to be horribly outdated (it suggests things that Rails now do automatically, etc.) The only output I get is this: Kakadu:ingenious_record adam$ rake test (in /Users/adam/Sites/1_PRK/vendor/plugins/ingenious_record) /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -Ilib:lib:test "/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake/rake_test_loader.rb" "test/ingenious_record_test.rb" The simplest test case looks like this: require 'test_helper' require 'active_record' class IngeniousRecordTest < ActiveSupport::TestCase test "example" do assert false end end This should definitely produce at least some output, and the only test in that file should produce a failed assertion. Any ideas what I could do to get Rails to run my tests?

  • Trouble with Rails has_many relationships

    - by Tchock
    I'm writing an app where a user can both create their own pages for people to post on, and follow posts on pages that users have created. Here is what my model relationships look like at the moment... class User < ActiveRecord::Base has_many :pages has_many :posts has_many :followings has_many :pages, :through => :followings, :source => :user class Page < ActiveRecord::Base has_many :posts belongs_to :user has_many :followings has_many :users, :through => :followings class Following < ActiveRecord::Base belongs_to :user belongs_to :page class Post < ActiveRecord::Base belongs_to :page belongs_to :user The trouble happens when I try to work my way down through the relationships in order to create a homepage of pages (and corresponding posts) a given user is following (similar to the way Twitter's user homepage works when you login - a page that provides you a consolidated view of all the latest posts from the pages you are following)... I get a "method not found" error when I try to call followings.pages. Ideally, I'd like to be able to call User.pages in a way that gets me the pages a user is following, rather than the pages they have created. I'm a programming and Rails newb, so any help would be much appreciated! I tried to search through as much of this site as possible before posting this question (along with numerous Google searches), but nothing seemed as specific as my problem...

  • Is it possible to use best_in_place with typeahead from twitter bootstrap?

    - by Dave H
    Basically, I am using best_in_place in my rails webapp to let users edit their profile info in place. The thing is, I would like users to be presented with a typeahead form for certain entries.. Here's what I'm working with: <p>College/University: <input type="text" class="span3" style="margin: 0 auto;" data-provide="typeahead" data-items="8" data-source='["University of Pennsylvania","Harvard","Yale","Princeton","Cornell","Brown","Columbia","Dartmouth"]'></p> This gives me a working form box with typeahead. However, I want to be able to wrap this in best_in_place with something like <%= best_in_place @student, :education %> so that users only see the typeahead form when they click on the text, and upon clicking away from the box or hitting enter the selection is stored in the database. Is there a reasonably easy way to do this?

  • Rails Counter Cache and its implementation

    - by Ishu
    Hello All, I am trying to get hold of rails counter cache feature but not able to grasp it completely. Let's say that We have 3 models A B C A belongs to B or C depending upon a field key_type and key_id. key_type tells whether A belongs to B or C so if key_type="B" then the record belongs to B otherwise it belongs to C. In my model a.rb, I have defined following associations: belongs_to :b, :counter_cache => true, :foreign_key => "key_id" belongs_to :c, :counter_cache => true, :foreign_key => "key_id" and in b and c model files has_many :as , :conditions => {:key_type => "B"} has_many :as , :conditions => {:key_type => "C"} Both B and C Models have a column as as_count The problem is every time an object of a is created count is increased in the both the models b and c. Any help is appreciated. Initially i thought that this may work: belongs_to :b, :counter_cache => true, :foreign_key => "key_id", :conditions => {:key_type => "B"} belongs_to :c, :counter_cache => true, :foreign_key => "key_id", :conditions => {:key_type => "C"} But this does not help.

  • ModelName(django.contrib.auth.models.User) vs ModelName(models.Model)

    - by amr.negm
    I am developing a django project. I created some apps, some of those are related to User model, for instance, I have a feeds app that handles user feeds, and another app that deals with extra user data like age, contacts, and friends. for each of these, I created a table that should be connected to the User model, which I using for storing and authenticating users. I found two ways to deal with this issue. One, is through extending User model to be like this: ModelName(User): friends = models.ManyToMany('self') ..... Two, is through adding a foreign key to the new table like this: ModelName(models.Model): user = models.ForeignKey(User, unique=True) friends = friends = models.ManyToMany('self') ...... I can't decide which to use in which case. in other words, what are the core differences between both?

  • Find which alias method is called in rails model

    - by Kashif Umair Liaqat
    I am new to rails development. I have created some aliases to a method and I want to know that which alias is called. I have this code. alias_method :net_stock_quantity_equals :net_stock_quantity alias_method :net_stock_quantity_gte :net_stock_quantity alias_method :net_stock_quantity_lte :net_stock_quantity alias_method :net_stock_quantity_gt :net_stock_quantity alias_method :net_stock_quantity_lt :net_stock_quantity def net_stock_quantity #some code here end I want to know that user has called which alias. Like if user calls net_stock_quantity_equals then I should know that the user has called net_stock_quantity_equals not net_stock_quantity. Any help would be appreciated.

  • Rails - how to use a plugin from github (how to install, utilize, etc)

    - by jyoseph
    I'm trying to install a couple of different plugins for my rails 3 app. I cd to '/vendor/plugins/', then type git clone the_git_src_url. I see the files in the /vendor/plugins/ directory. However when I try to use any of the tags provided by the plugin I get uninitialized constant ContentsController::HTMLToTextileParser PriceTag and html2textile are the two plugins I'm trying to use. This is what triggers the error above: <%= PriceTag.html_to_textile(@content.desc) %> I'm working in development, I've tried to restart the server. Is there something I'm missing?

  • Rails add a param to the end of a search query

    - by bob
    Hello, I am trying to implement a sort on the returned results of a search with rails. Filter by: 'recent' % | 'lowest_price' % | 'highest_price' % here are my links. I would like to add a filter to the end of my search query. So for example, I submit a search and I get back results and in my url I have http://localhost:3000/junks?search=handbag&condition=&category=&main_submit=Go! I would then like the user to be able to click one of the above links and have the page come back with a new query (i have this set up in the controller like such) con_id = params[:condition] if params[:category].nil? || params[:category].empty? cat_id = params[:category] results = Junk.search params[:search], :with => { :category_id => cat_id, :condition_id => con_id } case params[:filter] when "lowest_price" @junks = results.lowest_price.paginate :page => params[:page], :per_page => 12 when "highest_price" @junks = results.highest_price.paginate :page => params[:page], :per_page => 12 else @junks = results.paginate :page => params[:page], :per_page => 12 end else I would like the user to be able to click on of the above links and append a filter param to the end of the search query so that my controller can pick it up and call the correct database queries as seen in the case statement above. I'm guessing the url will look like this http://localhost:3000/junks?search=handbag&condition=&category=&main_submit=Go!&filter="lowest_price" How can I do this? Is there a better way?
