I currently have my index.html.erb showing the following code.
<select name="country">
<option>All</option>
<%= country_options_for_select('All') %>
</select>
But the result of the page becomes like this in the html source:
<select name="country">
<option>All</option>
<optionvalue="Afghanistan">Afghanistan</option><optionvalue="Aland
Islands">AlandIslands</option> ...
</select>
It should be instead of <option>
What did I do wrong?
Try using select_tag instead. It looks a bit cleaner.
<%= select_tag "name", country_options_for_select() %>
The reason the country options are showing up incorrectly is because you are passing 'All' to it. It doesn't need an argument there in your case. Only if you wanted a certain option selected by default.
For example,
<%= select_tag "name", country_options_for_select('Chile') %>
More info on it's use here: http://apidock.com/rails/ActionView/Helpers/FormOptionsHelper/country_options_for_select
In Rails 2.3.14 to Rails 3.1.0, this works:
<%= country_options_for_select.html_safe %>

I have a form without a model backing it built using form_with in Rails 6:
<%= f.text_field :one %>
<%= f.select :two, [['Option 1',1],['Option 2',2]] %>
<%= f.submit 'Submit' %>
The only documentation I can find to set which of the select options are selected by default says that it will pre-select whatever is in the model. Since I don't have a backing model, how can I choose which option is selected? I've poked around the options a little and found nothing, but I do not necessarily know where to look.
You must have missed it, there's an optional selected keyword argument.
Lastly, we can specify a default choice for the select box with the
:selected argument:
<%= form.select :city, [["Berlin", "BE"], ["Chicago", "CHI"], ["Madrid", "MD"]], selected: "CHI" %>
Output:
<select name="city" id="city">
<option value="BE">Berlin</option>
<option value="CHI" selected="selected">Chicago</option>
<option value="MD">Madrid</option>
</select>

I'm using simple-form (Ruby 2.5.1, Rails 5.2.3, simple-form 4.1.0) to generate checkboxes for an association. The form element it generates includes an overall title for the section that defaults to the name of the association (in this case, "Menu item tags") and is inside a tag. I want to hide it completely, but can't.
I can change the text to "Test" using label: "Test", but label: false doesn't hide it like I'd expect. I've read the docs and done my best to read the source, but I can't make any progress.
Here's the simple-form call:
f.association :menu_item_tags, as: :check_boxes
And here's the HTML output:
<fieldset class="form-group check_boxes optional listing_menus_menu_sections_menu_items_menu_item_tags form-group-valid">
<legend class="col-form-label pt-0">Menu item tags</legend>
<input type="hidden" name="listing[menus_attributes][0][menu_sections_attributes][0][menu_items_attributes][0][menu_item_tag_ids][]" value="">
<div class="form-check">
<input class="form-check-input is-valid check_boxes optional" type="checkbox" value="1" checked="checked" name="listing[menus_attributes][0][menu_sections_attributes][0][menu_items_attributes][0][menu_item_tag_ids][]" id="listing_menus_attributes_0_menu_sections_attributes_0_menu_items_attributes_0_menu_item_tag_ids_1">
<label class="collection_check_boxes" for="listing_menus_attributes_0_menu_sections_attributes_0_menu_items_attributes_0_menu_item_tag_ids_1">Vegetarian</label>
</div>
</fieldset>
I need to remove the tag on the second line of the HTML. label: false seems like the obvious convention, but it doesn't work.
Edit: This is not a duplicate of Remove outer label from collection_check_boxes. They're using a different function, getting different HTML out, and describing a different problem (that everything is wrapped in a label element). And the solution doesn't fix or affect the behavior I'm describing.
Edit: Here's a simplified version of the form in question, in response to a comment below:
<%= simple_form_for #listing do |f| %>
<%= f.simple_fields_for :menus do |f| %>
<%= f.simple_fields_for :menu_sections do |f| %>
<%= f.simple_fields_for :menu_items do |f| %>
<%= f.association :menu_item_tags, as: :check_boxes %>
<% end %>
<% end %>
<% end %>
<% end %>
= f.association :menu_item_tags, as: :check_boxes, legend_tag: false
You can eliminate the legend that is created by simple form with label: ""
You can do the following in css:
form[name="your_form_name"]>fieldset>legend {
display: none;
}
But it's purely cosmetic
;)
According to documentation:
label: false
should work to hide the generated <legend> element.
I tested this and found that this in fact does not work.
The workaround I found to work was:
label: ''
The <legend> element will still be generated but it will be blank.
I have the following select_tag and would like to have the labels translated. I am using Rails Internationalization (I18n) API
Now, this code works how ever I need to translate the option label.
<%= select_tag "object",
"<option value=address>Address</option>
<option value=Orden>Orden</option>".html_safe %>
I have tried:
<%= select_tag "object",
"<option value=address><%= t('address').capitalize %></option>
<option value=Orden>Orden</option>".html_safe %>
But I get a syntax error. I have also tried:
<%= select_tag "object",
"<option value=address> t('address').capitalize </option>
<option value=Orden>Orden</option>".html_safe %>
The last one will not translate and just put the string 't('address').capitalize'
Any advice?
You should look into options_for_select(args)
http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#method-i-options_for_select
options_for_select([[t('address'), "address"], ["orden", "orden"]], params[:the_selected_one])
you would do:
<%= select_tag("object", options_for_select([[t('address'), "address"], ["orden", "orden"]], param[:the_selected_one])) %>
Try using options_for_select instead raw HTML options.
Check code below.
select_tag "object", options_for_select([t('address').capitalize, "address"], [t('order').capitalize, "order"])
Also you can use a Model to build the Select options. Please, check the documentation below for more information.

I have the following form code
<%= f.fields_for resource.paid_account do |pa| %>
<%= pa.collection_select :account_plan_id, #account_plans, :id, :name_with_price %>
<% end %>
that generates the following HTML
<select id="user_paid_account_account_plan_id" name="user[paid_account][account_plan_id]">
<option value="2">Lite ($10.00/mo)</option>
<option value="3">Professional ($20.00/mo)</option>
<option value="4">Plus ($30.00/mo)</option>
</select>
Is user[paid_account][account_plan_id] the right name? Shouldn't it be user[paid_account_attributes][account_plan_id]?
I ask because this is causing problems on the backend; my account_plan record isn't getting created.
Looks like this answer is yes. I manually changed the name like this:
<%= pa.collection_select :account_plan_id, #account_plans, :id, :name_with_price, {},
{ name: "user[paid_account_attributes][account_plan_id]" } %>
and now it works. Feels like a hack, though, so it seems like there must be a better way to do it.
Today is the first day I'm looking into Ruby on Rails, and now I'm stuck. I have two scaffolds, artist and song.
In songs/new.html.erb, I have these lines:
...
<%= f.label :name %><br />
<%= f.text_field :name %>
...
<%= f.label :Artist %>
<%= collection_select(:song, :Artist, #artists, :id, :sort_name) %>
...
In the form for creating a new song, I want a <select> list with all artists. Using the code above works fine. The form is created as I want it, and the artists are listed. However, when submitting the new song, I get this error:
Artist(#69916999335860) expected, got String(#69917057438720)
The generated HTML code for the select looks like this:
<select id="song_Artist" name="song[Artist]">
<option value="1">Vreeswijk, Cornelis</option>
<option value="2">De lyckliga kompisarna</option>
<option value="3">Wiehe, Mikael</option>
<option value="4">Demian, Lars</option>
<option value="5">Sundström, Stefan</option>
</select>
I guess the second last parameter for collection_select() is wrong, but what should it be?
I think this should be:
<%= collection_select(:song, :artist_id, #artists, :id, :sort_name) %>
The second parameter is the method to be assigned in the model being created/updated. So in your controller the value would be retrieved from the params hash with params[:song][:artist_id]
A detailed explanation can be found in the Rails API docs under "collection_select"
