i'm new to rails and ruby, sorry if it's too noobish to ask but need help cause i'm stuck.
i have simple 'app', using rails forms. I need to change ( . ) into ( : ) whenever user will fill the text_field on form.
can anyone be so kind and help me create method from scratch, to access text_field : appearance and use gsub method on it to change ( . ) into ( : ) ?
here is my view: (model is empty, controller is generated using scaffold, super simple stuff)
<%= form_for(#sample) do |f| %>
<% if #sample.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#sample.errors.count, "error") %> prohibited this sample from being saved:</h2>
<ul>
<% #sample.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %><br>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :url %><br>
<%= f.text_field :url %>
</div>
<div class="field">
<%= f.label :appearance %><br>
<%= f.text_field :appearance %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
In your model, try this:
class Sample < ActiveRecord::Base
def appearance=(value)
write_attribute(:appearance, value.gsub(/\./, ':'))
end
end

I generated a scaffold for a portfolio via the Rails command, rails g portfolio titre:string, thumbnail:string lien:string description:text. I also added FriendlyId to get a better URL, and that's about all. Here is the 'update' action.
def update
if #portfolio.update(portfolio_params)
redirect_to #portfolio, notice: 'Portfolio mis à jour.'
else
render :edit
end
end
However, when trying to update a project in my portfolio, the submit button tries to get to 'portfolio#update' via patch, but puts a '.' instead of a '/' which gives me No route matches [PATCH] "/portfolios.test-1"
For the route, I only have resources :portfolios
edit : added the form
<%= form_for #portfolio, url: portfolios_path(#portfolio) do |f| %>
<% if portfolio.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(portfolio.errors.count, "error") %> prohibited this portfolio from being saved:</h2>
<ul>
<% portfolio.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :titre %>
<%= f.text_field :titre %>
</div>
<div class="field">
<%= f.label :categorie %>
<%= f.text_field :categorie %>
</div>
<div class="field">
<%= f.label :description %>
<%= f.text_area :description %>
</div>
<div class="field">
<%= f.label :thumbnail %>
<%= f.file_field :thumbnail %>
</div>
<div class="field">
<%= f.label :lien %>
<%= f.text_field :lien %>
</div>
<div class="actions">
<%= f.submit 'Enregistrer' %>
</div>
<% end %>
I didn't have any other possibilities that doing #portfolio, url: portfolios_path(#portfolio), otherwise Rails considered that '#portfolio' was nil
edit 2 : added the private 'set_portfolio' params
private
# Use callbacks to share common setup or constraints between actions.
def set_portfolio
#portfolio = Portfolio.friendly.find(params[:id])
end
What's wrong with my app ?
portfolios_path is the collection path.
change it portfolio_path should fix it.
<%= form_for #portfolio, url: portfolio_path(#portfolio) do |f| %>
I guess you are going to use this form for creating new portfolio as well, so change it to <%= form_for(#portfolio) %> should fix it and will also work for both cases. form_for will submit to correct path.
I have create an rails application with mongoid but im facing one problem at DATE
I created an scaffold with a name "posting"
When im editing date it will updated....
I follow the instruction of Railscast #238 Mongoid here
there is my posting.rb file
class Posting
include Mongoid::Document
field :title
field :description
field :comments
field :published, :type => Date
end
this my _from.html.erb
<%= form_for(#posting) do |f| %>
<% if #posting.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#posting.errors.count, "error") %> prohibited this posting from being saved:</h2>
<ul>
<% #posting.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :title %><br>
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :description %><br>
<%= f.text_field :description %>
</div>
<div class="field">
<%= f.label :published %><br>
<%= f.date_select :published %>
</div>
<div class="field">
<%= f.label :comments %><br>
<%= f.text_area :comments %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
and finally my show.html.erb file
<p id="notice"><%= notice %></p>
<p>
<strong>Title:</strong>
<%= #posting.title %>
</p>
<p>
<strong>Description:</strong>
<%= #posting.description %>
</p>
<p>
<strong>published:</strong>
<%= #posting.published %>
</p>
<p>
<strong>Comments:</strong>
<%= #posting.comments %>
</p>
<%= link_to 'Edit', edit_posting_path(#posting) %> |
<%= link_to 'Back', postings_path %>
What do you mean by not working? doesn't look like you have used published property in any of your views.
in your show.html.erb you are using
<%= f.date_select :pub %>
and in your show.html.erb you are using
<%= #posting.pub %>
However there is no property called pub in your Posting model. What you have there is called published
field :published, :type => Date
You either need to rename it in the model, or in the views to match.
I want to generate a dinamic field in my form on Rails. This is the code:
<%= form_for(#item) do |f| %>
<% if #item.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#item.errors.count, "error") %> prohibited this item from being saved:</h2>
<ul>
<% #item.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :vehicle %><br>
<%= f.text_field :vehicle %>
</div>
<div class="field">
<%= f.label :part %><br>
<%= f.text_field :part %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
My idea is put a script into the form where i can generate a field part dinamicaly with a button with a text like "add" for another part field. Any idea?? Thanks everyone.
I'm playing around with Form Helpers. I found some code from another SO question and thought it was pretty efficient at creating radio buttons with an elegant loop. Now that I've incorporated it, it doesn't save the data (e.g. the category value is not being saved to the project table)
Please see code below of _form.html.erb
<%= form_for(#project) do |f| %>
<% if #project.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#project.errors.count, "error") %> prohibited this project from being saved:</h2>
<ul>
<% #project.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :title %><br>
<%= f.text_field :title %>
</div>
<div class="form_row">
<label for="category">Category:</label>
<% [ 'checklist', 'process'].each do |category| %>
<br><%= radio_button_tag 'category', category, #category == category %>
<%= category.humanize %>
<% end %>
<br>
</div>
<div class="field">
<%= f.label :description %><br>
<%= f.text_field :description %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Your radio button parameter is being created outside of the project structure. If you look at params, you'll probably see
{:category => "your_category", :project => {...project params...}}
It is because you're using the radio_button_tag instead of the regular form helper. Try this instead:
f.radio_button :category, category, :checked => (#category == category)
Also, as Justin said, make sure :category is included in the project_params in your controller.
I have a simple app that allows users to create 'items'. On the _form, the only data that it asks for is 'content' and 'user_id', which is currently a number picker that assigns user_id to the item for ownership. But what I want to do is have the form assume that the user_id is the current user's ID (using Devise). That way other people can't assign 'items' to other users. Make sense? Here's the form.
_form.html.erb
<%= form_for(#item) do |f| %>
<% if #item.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#item.errors.count, "error") %> prohibited this item from being saved:</h2>
<ul>
<% #item.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :content %><br />
<%= f.text_field :content %>
</div>
<div class="field">
<%= f.label :user_id %><br />
<%= f.number_field :user_id %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
You should be working with associations from the model.
example your Items model should have belongs_to :user
then your would just use the :user method not the user_id attribute.
But you really could make this much more simpler.
install simple_forms gem it will make your life easier.
gem "simple_form"
then
<%= simple_form_for(#item) do |f| %>
<%= f.input :content %>
<%= f.association :user %>
<%= f.button :submit %>
<% end %>
