How do I create a collecton_select drop down to set the state of a resource in a form?
right now I have
<%= f.collection_select :state, Ticket.state.all, :event, :state_name_humanize, :prompt => true %>
(could pluginaweek make a 'getting started with state_machine' tutorial, I am really hot on using it, but I am a nube . . .)
From the example a collection select should look like this: <%= f.collection_select :access_state_event, #user.access_state_transitions, :event, :human_event, :include_blank => "don't change" %>
Would also like to see a simple example/tutorial for active record

Fairly new to rails, meaning I believe I have most of the basics down, but definitely still a student of the art.
What I'm trying to accomplish: append params to an existing form using form_for.
So, I need to find the id for an existing form and pass a new hash to this form using the JobsController to append several columns of data.
Steps are to select the job number from a select_box, add any changes/notes for that job using text_fields/check_boxes, then submit. Also view used is a partial, found in views/jobs.
Current problem, despite several attempts, is:
Overriding the default 'post' method --tried several combinations of the following: method => 'put', :action => update, :controller => :jobs
class Job < ActiveRecord::Base
attr_accessible :note, :twgid, :padd, :lnkbr, :txtwr, :datewr, :pinmiss, :headch, :name, :nucopy, :minrend, :majrend, :lnkwr, :gmail, :hotmail, :aol, :outlook, :note, :linkwr
belongs_to :form
end
JobsController:
( scaffolded )
View: (jobs/_form.html.erb)
<%= form_for #job do |f| %>
<fieldset>
<div class="form-horizontal">
<div class="control-group">
<span class="control-label">
<%= f.label :name, "TWGID" %></span>
<%= f.select :name, options_from_collection_for_select(Job.all, :name, :name), :prompt => 'Select' %>
</fieldset>
<fieldset>
<div class="control-group">
<span class="control-label">
<%= f.label :padd, "Add Padding?" %></span>
<%= f.check_box :padd %>
<%= f.hidden_field, :updated, :value => '1' %>
<% end %>

I'm not 100% sure what your trying to do but let me take a crack at it.
Well, the first thing I see is that in update_job on the first line you try grabbing a Change object and putting it into #change. The problem is that your using #change.id which obviously hasn't been set yet. If you are getting the id through params you will want to use:
#change = Change.find(params[:id])
Second, you are trying to update an attribute of Job but have a Change object. This will not work.
What I think your trying to do overall is to build a form that updates a change and will also update its associations (jobs in this case). A quick link on how to do this is here:
Form Helpers <--- Search for Nested Attributes Examples
Here is the code I would suggest:
<%= form_for #change do |f| %>
<%= f.fields_for :job do |j| %>
Updated : <%= j.check_box :updated %>
<% end %>
<% end %>
This will put the updated option in params[:change][:jobs_attributes] and when you send params[:change] into your update like so, #change.update_attributes(params[:change]) it will update your job as well.
I'm definitely a bit of a noob, so this might be something simple that I'm overlooking, however, the searches that I've done to try and find a solution have come up empty.
I've built a form using formtastic that has 5 input fields: two are text boxes and three are select lists.
<%= semantic_form_for #player do |f| %>
<%= f.inputs do %>
<%= f.input :firstname, :label => "First Name " %>
<%= f.input :lastname, :label => "Last Name " %>
<%= f.input :leagueid, :as => :select, :collection => League.all(:order => :leaguename), :label => "League " %>
<%= f.input :team_1, :as => :select, :collection => Team.all(:order => :name), :label => "Team 1 " %>
<%= f.input :team_2, :as => :select, :collection => Team.all(:order => :name), :label => "Team 1 " %>
<% end %>
<%= f.actions %>
<% end %>
What is happening is that the Teams lists work perfectly (the team names are displayed). However, the League list is a different story. All of the entries in the list look like this (with different a different code after 'League:'):
#<League:0x007fe29c406498>
If I use the form to create a Player, it works fine. The correct league ID goes into the database and everything. I just can't figure out why the names of the teams show, while whatever-that-is shows for the league.
Any and all help is appreciated.
When converting objects to String, Ruby will convert them to the memory address like you see unless you provide a to_s method for string conversions. I haven't used formtastic, but I believe adding a to_s method to your League class should cause it to display what you want.
Try adding
def to_s
#name # use whatever you want to be displayed.
end
to the League class.
You could try explicitly specifying the fields that should be used as the text and id within the select list. I believe it would look like.
<%= f.input :leagueid, :as => :select, :collection => Hash[League.all.map { |league| [league.leaguename, league.id] }]
The syntax is crazy. The call to map is returning an array of name/id pairs, like [ ['league1', 1], ['league2', 2] ]. Calling Hash on that converts it to a hash, like {'league1' => 1, 'league2' => 2}. Seems like the select list should use this hash to populate itself.
There's an example of this at http://rdoc.info/github/justinfrench/formtastic, under the Usage section.
:member_name is the solution I think.
<%= f.input :leagueid, :as => :select, :collection => League.all(:order => :leaguename), :label => "League " %>
Will probably work for you as
<%= f.input :leagueid, :as => :select, :member_name => :league, :collection => League.all(:order => :leaguename), :label => "League " %>
My problem was I have a model with a field the same name as the model and I think that confused Formtastic
Example scaffold:
rails g scaffold Countries code:string country:string
rails g scaffold Types title:string description:string
Model:
class Sign < ActiveRecord::Base
attr_accessible :title, :country_id, :type_id
belongs_to :country
belongs_to :type
Form View:
<%= f.input :type %>
<%= f.input :country, :member_label => :country %>
Having a form without the member_label leads to the object id displaying in the select box for countries although the ID is correctly saved. The type select worked perfectly without declaring member_label.
Note that I didn't need to specify :as => :select as formtastic can deduce this from the belongs_to relationship.
Try using :
<%= form.input :league, :member_label => :leaguename %>
This will override the naming convention of the Formtastic Column Select.
Have a look also at : Overriding the Column Name Convention wiki
Hope this helped.
I am new to rails and was wondering if someone could show me some light...
I have a simple form with couple of input fields and need to display field validation messages below the field name. Is there is a straightforward way to say display errors below??? or do i have to check for each field error message and create a span tag?
You can specify in your simple_form.rb initializer file with which tag your error message will be wrapped:
b.use :error, :wrap_with => { :tag => :span, :class => :error }
Also you can disable default error component on the input and print it by yourself like this:
<%= simple_form_for #user do |f| %>
<%= f.input :name, error: false %>
<%= f.error :name %>
<%= f.submit %>
<% end %>
and style your error message like you want.
I have the following in a partial in a Rails 3.2 app using formtastic gem
<%= f.semantic_fields_for :bucket do |bucket| %>
<%= bucket.inputs do %>
<%= bucket.input :bucket_name, :collection => #buckets,
:include_blank => false %>
<%= bucket.input :sub_directory, :collection =>
#buckets.first.paths,
:include_blank => false %>
<% end %>
<% end %>
right now in my controller I can get :bucket_name and the value is ==
to an integer, In my case I only have one item in my collection but it is giving me a value of 2. My guess is this is the ID value of the object.
it's important that I get the actual :name string value of the object
that is selected in the collection. I am not sure how to do this. so
let's say the item I select has a label of "my label" and it's the 3rd
item in the collection. how would I grab the value "my label".
By default, select inputs will use the id attribute of the model as the value attribute of the <option> tags, and it ties various methods on the object for the contents of the option tag such as to_label, name, and to_s.
You can change both with the :member_value and :member_label options respectively (these were called :value_method and :label_method in older versions.
The details of each option are in the documentation for the select input, which I assume you haven't looked at :)
http://rdoc.info/github/justinfrench/formtastic/Formtastic/Inputs/SelectInput
:member_value and :member_label are deprecated from v3 onwards of Formtastic.
Easiest way is to modify the collection passed into the input. See the example from formtastic github page
f.input :author, :as => :select, :collection => Author.pluck(:first_name, :id)
Here the first_name is the label and id is the value for the select options
I'm new to Rails and I've just spent another hour Googling and not finding an example.
So I have a simple form that I need to submit to an API. So I tried submitting it to the API directly but got advice that I do it in my app so I can do something with the results. Anyway, here's my simple form:
<%= form_tag(:action => 'submit') do |f| %>
<%= f.text_field :email, :value => "Your email address...", :class => "text", :id => "email", :name => 'email',
:onFocus => "change(this,'#222222'); this.value=''; this.onfocus=null;",
:size => "26" %>
<%= f.hidden_field :ref_code, :id => 'ref_code', :name => 'ref_code', :value => #referralid %>
<%= submit_tag "Enter To Win", :class => "button-positive submit" %>
<% end %>
Everything I'm seeing has forms that that use a model, I have no need to persist this data, just pass it on to the API.
So my thought was I just create an action in the home controller, where this page lives and have the action submit to it but I get a RoutingError and it's: No route matches {:action=>"submit", :controller=>"home"}
So what do I need to put in the Routes.rb? I tried:
namespace :home do
resources :submit
end
No Joy... I'm sure it's simple but I just can't find the right example.
I think that you should have a look at the ruby guides, it's very well explained (but I don't think it talks about API) and it will save you a lot of time in the future, I swear.
Not sure what you mean but I see some wired stuff, so I hope to be useful, but if you're following some tutorials from the net let us know the link.
Basically what I do is always to call an action of a controller (MVC), following this way you should have a controller (?? apis_controller ??) and call one action of it.
So you want to use form_tag instead of form_for because you're not addressing a model, therefor you want to get rid of f. and use suffix _tag (api).
<%= form_tag(send_api_path) do %>
<%= text_field_tag :email, "Your email address..." %>
<%= hidden_field_tag :ref_code, #referralid %>
<%= hidden_field_tag :api_name, 'your_api_name' %>
<%= submit_tag "Enter To Win" %>
<% end %>
Then, in your apis_controller.rb you create an action send where you send and manage your request.
#apis_controller.rb
def send
# TODO: your code here
end
Another thing is to set the routes, something like
#routes.rb
match 'apis/send' => 'apis#send', :as => :send_api
I'm sure this is not 100% working code, but it should be useful
How to call the api? I had I fast look and found this.
When you ask for help it's always good to attach the error you get, this makes it easier for people to understand the problem.
