  • current_user.user_type_id = @employer ID

    - by sscirrus
    I am building a system with a User model (authenticated using AuthLogic) and three user types in three models: one of these models is Employer. Each of these three models has_many :users, :as = :authenticable. I start by having a new visitor to the site create their own 'User' record with username, password, which user type they are, etc. Upon creation, the user is sent to the 'new' action for one of the three models. So, if they tell us they are an employer, we redirect_to :controller = "employers, :action = "new". Question: When the employer has submitted, I want to set the current_user.user_type_id equal to the employer ID. This should be simple... but it's not working. # Employers Controller / new def new @employer = Employer.new 1.times {@employer.addresses.build} render :layout => 'forms' end # Employers Controller / create def create @employer = Employer.new(params[:employer]) if @employer.save if current_user.blank? redirect_to :controller => "users", :action => "new" else current_user.user_type_id = @employer.id current_user.user_type = "Employer" redirect_to :action => "home", :id => current_user.user_type_id end else render :action => "new" end end ------UPDATE------ Hi guys. In response: I am using this table structure because each of my three user type models have lots of different fields and each has different relationships to the other models, which is why I've avoided STI. By 1.times (@employer.addresses.build) I'm connecting the employer model to the address polymorphic table in one form, so I'm asking the controller to build a new address to go along with the new employer. Averell: you mentioned encapsulating... something in the model using a 'setter' method. I have no idea what you mean by this - could you please explain how this works (or direct me to an example elsewhere)? With tsdbrown's answer I have managed to create the behavior I want... if there's a more elegant way to accomplish the same thing I'd love to learn how. Thanks very much. Thanks to tsdbrown for answering the current_user.save problem!

  • Format form fields for bootstrap using rails+nokogiri

    - by user1116573
    I have the following in an initializer in a rails app that uses Twitter bootstrap so that it removes the div.field_with_errors that rails applies when validation fails on a field but also the initializer adds the help/validation text after the erroneous input field: require 'nokogiri' ActionView::Base.field_error_proc = Proc.new do |html_tag, instance| html = %(<div class="field_with_errors">#{html_tag}</div>).html_safe form_fields = [ 'textarea', 'input', 'select' ] elements = Nokogiri::HTML::DocumentFragment.parse(html_tag).css("label, " + form_fields.join(', ')) elements.each do |e| if e.node_name.eql? 'label' html = %(#{e}).html_safe elsif form_fields.include? e.node_name if instance.error_message.kind_of?(Array) html = %(#{e}<span class="help-inline">&nbsp;#{instance.error_message.join(',')}</span>).html_safe else html = %(#{e}<span class="help-inline">&nbsp;#{instance.error_message}</span>).html_safe end end end html end This works fine but I also need to apply the .error class to the surrounding div.control-group for each error. My initializer currently gives the following output: <div class="control-group"> <label class="control-label" for="post_message">Message</label> <div class="controls"> <input id="post_message" name="post[message]" required="required" size="30" type="text" value="" /><span class="help-inline">&nbsp;can't be blank</span> </div> </div> but I need something adding to my initializer so that it adds the .error class to the div.control-group like so: <div class="control-group error"> <label class="control-label" for="post_message">Message</label> <div class="controls"> <input id="post_message" name="post[message]" required="required" size="30" type="text" value="" /><span class="help-inline">&nbsp;can't be blank</span> </div> </div> The solution will probably need to allow for the fact that each validation error could have more than one label and input that are all within the same div.control-group (eg radio buttons / checkboxes / 2 text fields side by side). I assume it needs some sort of e.at_xpath() to find the div.control-group parent and add the .error class to it but I'm not sure how to do this. Can anyone help? PS This may all be possible using the formtastic or simple_form gems but I'd rather just use my own html if possible. EDIT If I put e['class'] = 'foo' in the if e.node_name.eql? 'label' section then it applies the class to the label so I think I just need to find the parent tag of e and then apply an .error class to it but I can't figure out what the xpath would be to get from label to its div.control-group parent; no combination of dots, slashes or whatever seems to work but xpath isn't my strong point.

    This is probably pretty simple, but here: Say I've got two models, Thing and Tag class Thing < ActiveRecord::Base has_and_belongs_to_many :tags end class Tag < ActiveRecord::Base has_and_belongs_to_many :things end And I have an instance of each. I want to link them. Can I do something like: @thing = Thing.find(1) @tag = Tag.find(1) @thing.tags.add(@tag) If not, what is the best way to do this? Thanks!

  • How to change last letter of filename to lowercase if it is a letter?

    - by Robert Buckley
    I have been given data which cannot be interpreted by my software unless it has a lowercase letter at the end. The data was delivered with an uppercase letter at the end. Somehow I need to first recursively loop through all folders and find whether the filename ends with a letter and then change it to lowercase. I think python could do this, but I don´t know how,. Any help would be great! yours, Rob
