Is it possible to check submission before showing this simple form:
<%= form_for #article, url: {action: "create"}, html: {class: "nifty_form"} do |f| %>
<%= f.text_field :title %>
<%= f.text_area :body, size: "60x12" %>
<%= f.submit "Create" %>
<% end %>
like if its already submitted first time show other html content instead ?
Test the object. If you're using ActiveRecord/Mongoid:
<% if #article.new_record? %>
... display form ...
<% else %>
... do something different ...
<% end %>

I want to render a partial for each conversation. I have the following code:
# app/views/messages/_new.html.erb
<%= simple_form_for [#conversation, #message] do |f| %>
<%= f.text_area :body %>
<%= f.text_field :messageable_id, value: current_user.id, type: "hidden" %>
<%= f.text_field :messageable_type, value: "#{current_admin_user.class.name}", type: "hidden" %>
<%= f.submit "Send Reply" %>
<% end %>
I want to change value of both hidden text fields depends on passed variable. Something like:
# app/views/admin/conversations/_show.html.erb
<%= render 'messages/new', value: current_admin_user.id %>
With below code I'm getting an error Validation failed: Messageable must exist which means messageable_id = nil
Because you are not using the value you are passing to the partial.
Also, you need to pass both the variables
Try replacing the partial with the following
# app/views/admin/conversations/_show.html.erb
<%= render 'messages/new', messageable_id: current_admin_user.id, messageable_type: "#{current_admin_user.class.name}" %>
and use them
# app/views/messages/_new.html.erb
<%= simple_form_for [#conversation, #message] do |f| %>
<%= f.text_area :body %>
<%= f.text_field :messageable_id, value: messageable_id, type: "hidden" %>
<%= f.text_field :messageable_type, value: messageable_type, type: "hidden" %>
<%= f.submit "Send Reply" %>
<% end %>
NOTE: If you want the _new partial to render on its own as well
replace it with something like this:
<% messageable_id ||= current_admin_user.id %>
<% messageable_type ||= "#{current_admin_user.class.name}" %>
<%= f.text_field :messageable_id, value: messageable_id, type: "hidden" %>
...
I use the following form_for at one point in my code to display a series of topics for users to select from.
<%= form_for #user do |f| %>
<%= f.collection_check_boxes(:topic_ids, Topic.all.sample(50).each, :id, :topic_name) %>
<%= f.submit %>
<% end %>
When it renders on the page, the boxes are all one-after-the-other. How can I separate them so that there is one check box per line?
from reference here
It is possibly to customize the way the elements will be shown by giving a block to the method as sample below from your code above
<%= form_for #user do |f| %>
<%= f.collection_check_boxes :topic_ids, Topic.all.sample(50).each, :id, :topic_name do |b| %>
<%= b.label(class: "check_box") do %>
<%= b.check_box(class: "check_box") %>
<%= b.object.topic_name %></br>
<% end %>
<% end %>
<%= f.submit %>
<% end %>
You may of course render HTML inside the block:
<%= form_for #user do |f| %>
<%= f.collection_check_boxes :topic_ids, Topic.all.sample(50).each, :id, : topic_name do |b| %>
<div class="my-checkbox-wrapper">
<%= b.label(class: "foo") do %>
<%= b.object.topic_name %>
<%= b.check_box(class: "bar") ></br>
<%end%>
<%= f.submit %>
<%end%>
You can have a look at this example
It is very broad question. In short, using CSS.
For example using Bootstrap 4:
<%= form_for #user do |f| %>
<div class="form-check">
<%= f.collection_check_boxes :topic_ids, Topic.all.sample(50).each, :id, :topic_name, class: 'form-check-input' %>
</div>
<%= f.submit %>
<% end %>
I'm working on a project where I'm trying to implement a voting system, but I'm having some trouble, I've tried creating a form with a hidden field:
<% form_for :vote, url: votes_path do |f| %>
<%= f.hidden_field :rating, value: '1' %></td>
<%= form_submit_button("vote 1") %>
<% end %>
But when I run that the submit button does not appear, I'm not really sure what I'm doing wrong.
form_for generates <FORM> tag, so you need to include its output with <%=:
<%= form_for :vote, url: votes_path do |f| %>
Use this code:
<%= form_for :vote, url: votes_path do |f| %>
<%= f.hidden_field :rating, value: '1' %></td>
<%= form_submit_button("vote 1") %>
<% end %>
= is usually shows the form in view page, if you remove it then any input tag will not be displayed.
I have information that is passed to a controller method but isn't saved to the DB. I want to access this information, that is passed to the controller method as a whole hash, but it is all individual data as you will see below.
Here is the params:
Parameters: {"utf8"=>"✓", "authenticity_token"=>"0O7pbNNrddHCyPL9B/avUUD85574rFBfS57h+aWKK/mBakPSn5iHJKHhPmvuJVfyWxjBsAQn2kagwkTOALEKRg==", "page"=>{"content_top"=>"", "content_bottom"=>""}, "header1"=>"iijijij", "column1"=>"ijijijij", "header2"=>"", "column2"=>"", "header3"=>"", "column3"=>"", "header4"=>"", "column4"=>"", "commit"=>"Save", "guide_id"=>"dungeon-boss", "category_id"=>"heroes", "id"=>"link-skill"}
As you can see there is a page hash and after, it is header1 column1 header2 column2... and so on. With the header1 info, I'm trying to put it inside a params hash like the page hash has for the values passed in it. So it's like "table" =>{"header1"=>"iijijij", "column1"=>"ijijijij", "header2"=>"", "column2"=>"", "header3"=>"", "column3"=>"", "header4"=>"", "column4"=>""}
I'm sure there is something I need to add to the form so it know to group them like this. Here is the form I currently have
<% if (current_user.mod_of_game?(#guide) unless current_user.nil?) %>
<%= form_for([#category, #page], url: update_pages_path) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<%= f.label :content_top, "Top Content" %>
<%= f.text_area :content_top, :class => 'editor' %>
<%= f.label :content_bottom, "Bottom Content" %>
<%= f.text_area :content_bottom, :class => 'editor' %>
<!-- to be in one hash when passed -->
<%= text_field_tag :header1 %>
<%= text_field_tag :column1 %>
<%= text_field_tag :header2 %>
<%= text_field_tag :column2 %>
<%= text_field_tag :header3 %>
<%= text_field_tag :column3 %>
<%= text_field_tag :header4 %>
<%= text_field_tag :column4 %>
<!-- end -->
<%= f.submit "Save" %>
<% end %>
I cant find what I need to add to make the text_field_tag data all be in one hash when passed.(the text_field_tag is purposely not being saved to the DB on form submit, it just needs to be passed to the method and grouped inside a hash)
how about using fields_for like this
<%= form_for([#category, #page], url: update_pages_path) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<%= f.label :content_top, "Top Content" %>
<%= f.text_area :content_top, :class => 'editor' %>
<%= f.label :content_bottom, "Bottom Content" %>
<%= f.text_area :content_bottom, :class => 'editor' %>
<!-- to be in one hash when passed -->
<%= f.fields_for :table do |t| %>
<%= t.text_field_tag :header1 %>
<%= t.text_field_tag :column1 %>
<%= t.text_field_tag :header2 %>
<%= t.text_field_tag :column2 %>
<%= t.text_field_tag :header3 %>
<%= t.text_field_tag :column3 %>
<%= t.text_field_tag :header4 %>
<%= t.text_field_tag :column4 %>
<% end %>
<!-- end -->
<%= f.submit "Save" %>
<% end %>
You can simply use the array way if you want to send the data that doesn't belong to the model, in params hash inside page key. Here's how:
<%= text_field_tag 'page[header1]' %>
Not only this, if you would like to use another key, you can use that as well like <%= text_field_tag 'custom_key[header1]' %>
This is probably simple, I'm still coming to terms with rails syntax. What is the right syntax to pass the address_id in the url for form_for to a modified route?
This is the form - note the "address_id parameter"
<div class="one_fourth floatcenter">
<%= form_for address, :url => edit_address_path(:id => address.id), :method => :get do |f| %>
<%= content_tag(:button, :class => 'btn btn-inverse') do %> Edit Address
<% end %>
<% end %>
</div>
And this is the route I've configured:
get "edit_address/:id" => "member/addresses#edit"
Id is not being passed to the controller for some reason...
form_for address should be enough if address is a persisted object, but if it's not enough, then form_for address, url: edit_address_path(address) is what you want.
This is very simple. In place of url, you put your post method route:
<%= form_for(#post, url: super_posts_path) do |f| %>
...
<% end %>
You also call by action
<%= form_for #friend,:url=> { action: "create_friend"} do |f|%><br>
<%= f.label :u_from %>
<%= f.text_field :u_from %>
<%= f.label :u_to %>
<%= f.text_field :u_to %>
<%= f.submit%>
<% end %>
