My question template lists answers, and lets somone add a new answer for a question.
But I'm not sure where and how to initialize a new answer for this line:
<%= link_to 'New answer', new_question_answer_path(#question, Answer.new) %>
from the context below:
<p>
<b>Body:</b>
<%=h #question.body %>
</p>
<h1>Listing answers</h1>
<table>
<tr>
<th>Body</th>
</tr>
<% #question.answers.each do |answer| %>
<tr>
<td><%=h answer.body %></td>
<td><%= link_to 'Show', answer %></td>
<td><%= link_to 'Edit', edit_answer_path(answer) %></td>
<td><%= link_to 'Destroy', answer, :confirm => 'Are you sure?', :method => :delete %></td>
</tr>
<% end %>
</table>
<br />
<%= link_to 'New answer', new_question_answer_path(#question, Answer.new) %>
<%= link_to 'Edit', edit_question_path(#question) %> |
<%= link_to 'Back', questions_path %>
If I initialize the new Answer like this:
<%= link_to 'New answer', new_question_answer_path(#question, Answer.new) %>
the URL of the next page is garbled with an inspect call to the new Answer.
Try this:
<%= link_to 'New answer', new_question_answer_path(#question) %>

I am learning to code in ruby on rails environment. I created two models cars and products. I want to have a main page which have a link to cars and products. On clicking each of them they should display their own view pages. Below are view pages for cars and users respectively :
app/views/cars/index.html.erb
<p id="notice"><%= notice %></p>
<h1>Listing Cars</h1>
<table>
<thead>
<tr>
<th>Make</th>
<th>Color</th>
<th>Year</th>
<th colspan="24"></th>
</tr>
</thead>
<tbody>
<% #cars.each do |car| %>
<tr>
<td><%= car.make %></td>
<td><%= car.color %></td>
<td><%= car.year %></td>
<td><%= link_to 'Show', car %></td>
<td><%= link_to 'Edit', edit_car_path(car) %></td>
<td><%= link_to 'Destroy', car, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
</table>
<br>
<%= link_to 'New Car', new_car_path %>
<h4>Import that data!</h4>
<%= form_tag import_users_path, multipart: true do %>
<%= file_field_tag :file %>
<%= submit_tag "Import CSV" %>
<% end %>
</div>
app/views/users/index.html.erb
<p id="notice"><%= notice %></p>
<h1>Listing Users</h1>
<table>
<thead>
<tr>
<th>User</th>
<th>Steps</th>
<th>Distance</th>
<th>Minutes Exercised</th>
<th>Hours of Sleep</th>
<th>Calories Burned</th>
<th colspan="24"></th>
</tr>
</thead>
<tbody>
<% #users.each do |user| %>
<tr>
<td><%= user.user %></td>
<td><%= user.steps %></td>
<td><%= user.distance %></td>
<td><%= user.exercise %></td>
<td><%= user.sleep %></td>
<td><%= user.calories %></td>
<td><%= link_to 'Show', user %></td>
<td><%= link_to 'Edit', edit_user_path(user) %></td>
<td><%= link_to 'Destroy', user, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
</table>
<br>
<%= link_to 'New User', new_user_path %>
<div>
<h4>Import that data!</h4>
<%= form_tag import_users_path, multipart: true do %>
<%= file_field_tag :file %>
<%= submit_tag "Import CSV" %>
<% end %>
</div>
<%= form_tag import_users_path, multipart: true, class: 'form-inline' do %>
<div class="form-group">
<%= link_to "Export CSV", users_path(format: "csv"), class: 'btn btn-primary' %>
</div>
<% end %>
I don't know how to create single main page and provide links to these views. One example would help me. Thanks in advance guys.
Say suppose you have a main page named home
In your home.html.erb write
<%= link_to "cars" cars_path %>
<%= link_to "users" users_path %>
You probably should use rails scaffold to have a look at the functional pages generated by it at first.
Try this .......
<%=link_to "cars" cars_path(car) %>
<%=link_to "users" users_path(user) %>
This link will send you to show method of the controller (users/cars). Then you need to create a show page in your views/cars/show.html.erb and views/users/show.html.erb then you can display their own view/show pages.
Hope this will work for you.
You need to understand concept of routes in rails.
Run command rake routes in your project folder. You will see mapping like this.
Prefix Verb URI Pattern Controller#Action
companies GET /companies(.:format) companies#index
So according to routes, following link will lead to index action of companies controller.
<%= link_to 'Companies', companies_path%>
As you can observe, in companies_path, companies is prefix shown in routes.
For your specific case, following links will work. In your
home.html.erb
<%=link_to "All Cars", cars_path%>
<%=link_to "All Users", users_path%>
Remember there is comma between "All Users" and users_path. Because link_to is just a method with multiple arguments.

Yesterday i made some experience with carrierwav, all works fine but at the image tag where normally only the image should displayed rails also shows the hole model, with created_at etc. Here you cann see it!
So now my view:
<% #patient.treatments.each do |treatment| %>
<tr>
<td><%= treatment.category.try(:typ) %></td>
<td><%= treatment.content %></td>
<td><%= treatment.day %></td>
<td><div class="arrow"></div></td>
</tr>
<tr>
<td colspan="5">
<%= link_to 'Löschen', [treatment.patient, treatment],
:confirm => 'Sind sie sicher?',
:method => :delete %>
<%= treatment.paintings.each do |paint| %>
<%= image_tag paint.name %>
<% end %>
</td>
</tr>
<% end %>
The problem has to be in <%= image_tag paint.name %>
Remove the = from <%= treatment.paintings.each do |paint| %>, that is making you also print the treatment.paintings array.
<% treatment.paintings.each do |paint| %>
<%= image_tag paint.name %>
<% end %>
I want exibe the action 'Show' of scaffold in my index using ajax but when i click in show dont appear nothing my files is:
finances_controller.rb
def show
#finance = Finance.find(params[:id])
end
_show.html.erb
<p id="notice"><%= notice %></p>
<p>
<b>Date update:</b>
<%= #finance.updated_at %>
</p>
<p>
<b>Money:</b>
<%= #finance.money %>
</p>
<p>
<b>Entrance:</b>
<%= #finance.entrance %>
</p>
<p>
<b>Description:</b>
<%= #finance.description %>
</p>
<p>
<b>Situation:</b>
<%= #finance.situation %>
</p>
<p>
<b>Local:</b>
<%= #finance.local %>
</p>
<%= link_to 'Edit', edit_finance_path(#finance) %> |
<%= link_to 'Back', finances_path %>
my
index.html.erb modified the button show:
Bem vindo <%= session[:user_name]%>
<div id='list' align='left'>
<h1>Finanças - Hoje é dia <%= Date.today %></h1>
<%= link_to 'New Finance', new_finance_path %>
<table cellpadding="5" >
<tr>
<th>Data de Inserção</th>
<th>Caixa</th>
<th>Entrada</th>
<th>Descrição</th>
<th>Situação</th>
<th>Local</th>
<th></th>
<th></th>
<th></th>
</tr>
<% #finances.each do |finance| %>
<tr>
<td><%= finance.created_at %></td>
<td><%= finance.money %></td>
<td><%= finance.entrance %></td>
<td><%= finance.description %></td>
<td><%= finance.situation %></td>
<td><%= finance.local %></td>
<td><%= link_to 'Show', finance,:action => 'show',:id => #finance , :remote =>:true %></td>
<td><%= link_to 'Edit', edit_finance_path(finance) %></td>
<td><%= link_to 'Destroy', finance, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</table>
<br />
</div>
<div id='tools' align='right'>
<%if #finance %>
<%= render('show') %>
<% end %>
</div>
<%= link_to 'Logout', new_session_url,method: :delete %>
when i click in the show appear the url 'localhost:3000/finances/1' but dont happening nothing when i click this i want click and show my partial 'show' in the same page, i render the partial 'show' if especified the #finance ,
<%if #finance %>
<%= render('show') %>
<% end %>
try to use = render 'finances/show'
I'm following Railscasts Episode #165 Edit Multiple but having issue where when I go to the product index page it is not showing my list of products. I'm getting only the header and the link to new product. Any idea what I did wrong?
By the way I'm using rails 3.2.3
Thank you.
routes.rb
resources :products do
collection do
post :edit_multiple
put :update_multiple
end
end
resources :categories
index.html.erb
<h1>Listing products</h1>
<% form_tag edit_multiple_products_path do %>
<table>
<tr>
<th></th>
<th>Name</th>
<th>Category</th>
<th>Price</th>
</tr>
<% for product in #products %>
<tr>
<td><%= check_box_tag "product_ids[]", product.id %></td>
<td><%= product.name %></td>
<td><%= product.category.name %></td>
<td><%= product.price %></td>
<td><%= link_to "Edit", edit_product_path(product) %></td>
<td><%= link_to "Destroy", product, :confirm => 'Are you sure?', :method => :delete %></td>
</tr>
<% end %>
</table>
<%= submit_tag "Edit Checked" %>
<% end %>
<p><%= link_to "New Product", new_product_path %></p>
You need <%= form_tag ... instead of <% form_tag .... Without the = the return value (i.e. your form) is discarded rather than added to the output.
I think this is typo.
you forgot to use "=" You should do <%= form_tag edit_multiple_products_path do %>
I'm very new to rails so hopefully this should be a quick fix. I'm writing an application that searches a database and reloads the page displaying the desired results. In rails how does one save a input into a text_field and post it so that it can be retrieved and used in the query for retrieving data.
My view:
<title></title>
</head>
<body>
Search Collection <br>
<%= text_field "person", "name" %>
<%= select_tag(:search_id, '<option value="0">Search by</option><option value="1">Make</option><option value="2">Condition</option>
<option value="3">Sport</option>') %>
<%= link_to 'New catalog', new_catalog_path %>
<br>
<br>
<%= link_to "Search", :search_text => , :action => :index %> <br>
<br>
<h1>Results</h1>
<%= will_paginate #catalogs %>
<table border="1">
<tr>
<th>Catalog id</th>
<th>Year</th>
<th>Make</th>
<th>Card number</th>
<th>Number</th>
<th>Condition</th>
<th>Sport</th>
<th>Tracking list</th>
</tr>
<% for catalog in #catalogs %>
<tr>
<td><%= catalog.Catalog_ID %></td>
<td><%= catalog.Year %></td>
<td><%= catalog.Make %></td>
<td><%= catalog.Card_Number %></td>
<td><%= catalog.Number %></td>
<td><%= catalog.Condition %></td>
<td><%= catalog.Sport %></td>
<td><%= catalog.Tracking_List %></td>
<td><%= link_to 'Show', catalog %></td>
<td>
<%= link_to 'Edit', edit_catalog_path(catalog) %></td>
<td>
<%= link_to 'Destroy', catalog, :confirm => 'Are you sure?', :method => :delete %></td>
</tr>
<% end %>
</table>
<br>
</body>
My Controller method
def index
#search_text = 'T206 White Border'
#catalogs = Catalog.paginate_by_sql ['select * from catalogs where Make =\''+ #search_text+'\'' , 80000], :page => params[:page]
end
Be gentle if its an easy fix, I'm still getting used to the whole MVC thing
Your question has a lot going on, so let's try to sort through it one piece at a time. First, I'll assume your database has a table called catalogs with a column called make, and that you're using the will_paginate plugin. It looks like you got started by copying and modifying some examples straight from the docs. First, your controller - you don't need the more complex paginate_by_sql, you can use the simpler paginate.
controller:
def index
#catalogs = Catalog.paginate(:all, :conditions => {:make => params[:search]}, :page => params[:page])
end
Now your view, just the stuff relevant to the search:
<% form_tag catalogs_path, :method => :get do %>
<%= text_field_tag 'search' %>
<%= submit_tag 'submit search' %>
<% end %>
And that's it. Good luck!
