So I have a list of projects, and I try to make an each do in wich each of them should lead to its own project, but instead I get an error 'unexpected keyword_ensure', expecting end-of-input
, however, I keep checking them all and none seems to be missing.
<h1 id=title>Projects</h1>
<div id="post_wrap" class="skiny_wrap">
<% #projects.each do |project| %>
<div class="post">
<h2 class="name"><%= project.name %> </h2>
<p class="description"><%= project.description %> </p>
<% if project.has_photo? %>
<%= link_to project.name, project do %>
<div class="img_container" style="background-image: url(/photo_store/<%=project1.id%>.<%=project1.extension%>)"></div>
<% end %>
<%else%>
<p> theres nothing here </p>
<%end%>
<p class="category"><%= project1.category %> </p>
<p class="date"><%= project1.created_at.strftime('%A, %B %d') %> </p>
<hr>
</div>
<%end%>
<% end %>
</div>
What is going wrong? I can imagine one, is that that is not how you are meant to link to show however it is what my investigation lead to, please help me out.
<br><br>
<h2><%=#project.name%></h2>
<br>
<%=#project.link%>
<br><br>
<%=#project.description%>
<br><br>
Theme: <%=#project.category%>
<br><br>
<%= link_to "Edit", edit_post_path(#project) %>
<%= link_to "Delete", post_path(#project), method: :delete, data:{ } %>
That is the Erb to the show, as you can see is very simple..

cant view reply or comment section
Rails doesn't include a markdown method. You'll have to use a gem, write something yourself or a combination of the two. You could for example use the redcarpet gem, or one of the other markup processor gems.
Then write your own helper using this using this gem.
# app/helpers/markdown_helper.rb
module MarkdownHelper
MARKDOWN = Redcarpet::Markdown.new(Redcarpet::Render::HTML)
def markdown(markdown_string)
MARKDOWN.render(markdown_string).html_safe
end
end
For usage and possible render configurations checkout out the redcarpet documentation.
With this helper present you can simply do the following in the view:
<%= markdown(#discussion.content) %>
I have a blog rails app where users can comment on an article and the article author can message the user directly from the comment for which i have added a send message button, i am using mailbox for getting the message option, everything is working but the problem is when there are multiple comments the message button also get multiplied, but i don't want that what i am trying to have is one message button for each comment.
This is what am getting right now:
my code
<div id="comments">
<h2 class="comment_count">
<%= pluralize(#shipment.comments.count, "Bid") %>
</h2>
<% #comments.each do |comment| %>
<div class="comment">
<li class="round-image-50"><%= image_tag(current_user.avatar.url(:thumb)) %></li><h6 class="username"><strong><font style="text-transform: capitalize;"><%= comment.user.full_name %></strong></font></h6>
<div class="shipment">
<p class="content">
<div class="text-center left col-md-4">
<%= comment.content %>
</div>
<% if #shipment.user == current_user %>
<% #shipment.comments.each do |comment| %>
<%= link_to 'Send Message', new_conversation_path(recipient_id: comment.user_id), class: "btn btn-default btn-xs" %>
<% end %>
<% end %>
</p>
</div>
</div>
<% end %>
<%= render "comments/form" %>
</div>
Change this:
<% if #shipment.user == current_user %>
<% #shipment.comments.each do |comment| %>
<%= link_to 'Send Message', new_conversation_path(recipient_id: comment.user_id), class: "btn btn-default btn-xs" %>
<% end %>
<% end %>
to
<% if #shipment.user == current_user %>
<%= link_to 'Send Message', new_conversation_path(recipient_id: comment.user_id), class: "btn btn-default btn-xs" %>
<% end %>
PS: I assumed that #comments is same as #shipment.comments from your shown code
I need to refactor this code by using link_to method.
<a href="post.html">
<h2 class="post-title">
<%= post.title %>
</h2>
<h3 class="post-subtitle">
<%= post.subheading %>
</h3>
</a>
I want it to look like this:
<%= link_to ".........",post) %>
The "......" will be the refactored code.
You need to pass a block to the link_to:
<%= link_to post_url(#post) do %>
<h2 class="post-title">
<%= post.title %>
</h2>
<h3 class="post-subtitle">
<%= post.subheading %>
</h3>
<% end %>
I have created commenting system to provide functions like creating comments and replying them.
I used http://www.sitepoint.com/nested-comments-rails/ guide. Worked just perfect. But in this example to reply to some comment it goes to other path, that is what I want to avoid.
Code so far:
Advertisement#show here I want to create reply to comment.
<%= comments_tree_for #comments %>
<h1>New comment</h1>
<%= render 'comments/form' %>
_comment.html.rb
<div class="well">
<h2><%= comment.title %></h2>
<p class="text-muted"><%= comment.root? ? "Started by" : "Replied by" %> <strong><%= comment.author %></strong> on
<%= l(comment.created_at, format: '%B, %d %Y %H:%M:%S') %></p>
<blockquote>
<p><%= comment.body %></p>
</blockquote>
<% from_reply_form ||= nil %>
<% unless from_reply_form %>
<% if comment.leaf? %>
<small class="text-muted">There are no replies yet - be the first one to reply!</small>
<% end %>
<p><%= link_to 'reply', new_comment_path(comment.id) %></p>
<% end %>
</div>
_form.html.erb
<%= form_for(#comment) do |f| %>
<% if #comment.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#comment.errors.count, "error") %> prohibited this comment from being saved:</h2>
<ul>
<% #comment.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%= f.hidden_field :advertisement_id, :value => #advertisement.id%>
<%= f.hidden_field :user_id, :value => current_user.id%>
<%= f.hidden_field :parent_id %>
<div class="form-group">
<%= f.label :body %>
<%= f.text_area :body, class: 'form-control', required: true %>
</div>
<%= f.submit class: 'btn btn-primary' %>
<% end %>
Is there any trustworthy guide to help me ?
The link_to 'reply', new_comment_path(comment.id) line creates a hyperlink to new comment page and when clicked it takes you to next page to create the comment. Instead you can replace it with a div containing the form the toggles and submits new convo from the same page. Bootstrap comes handy here.
A Mock up of the idea: http://jsfiddle.net/bpya4fce/1/
You can build up using this idea. Hope this helps :)
P.S: Make sure that you fetch the variables required for the form in the action of view where you embed the form, i.e if you're embedding the form in show.html.erb, ensure the necessary variables are fetched in the show action/method of controller. In the earlier scenario, it'll be fetched in the new action of the CommentsController.
<div class="container">
<blockquote>
<h2>Posted Comment</h2>
Lorem Ipsum. You can reply to this below.
</blockquote>
<div class="panel-group" id="accordion">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion"
href="#collapseOne">
Click to reply
</a>
</h4>
</div>
<div id="collapseOne" class="panel-collapse collapse">
<div class="panel-body">
### The comment form comes here ###<br/>
### render :partial => 'comment/form'
</div>
</div>
</div>
</div>
Not sure if this is what you wanted. Hope this example code gives you some idea.
Be sure to complete the code and test it :)
_comment.html.rb
<% from_reply_form ||= nil %>
<% unless from_reply_form %>
<% if comment.leaf? %>
<small class="text-muted">There are no replies yet - be the first one to reply!</small>
<% end %>
<!-- HERE adding a hidden DIV that contains a form. -->
<div class='hidden-reply-form-<%= comment.id%>'>
<%= render partial: 'comments/form', locals: {comment: Comment.new} %>
</div>
<p><%= link_to 'reply', new_comment_path(comment.id), class: 'reply', id: comment.id %></p>
<% end %>
</div>
<script>
// HERE use reply link to toggle the hidden div.
$(function(){
$(".reply").click(function(){
// toggle replying div.
// .....
});
})
</script>
I've been able to jump most hurtles as I move through the Hartl Rails tutorial, but I can't figure out what I'm doing wrong around 10.4. I can get everything to render correctly using this /static_pages/home.html.erb
<% if signed_in? %>
<div class="row">
<aside class="span4">
<section>
<%= render 'shared/user_info' %>
</section>
<section>
<%= render 'shared/micropost_form' %>
</section>
</aside>
</div>
<% else %>
<div class="center hero-unit">
<h1>Welcome to The Gentle Introduction Resource</h1>
<p>
This is the home page for the
The Gentle Introduction Resource
web app.
</p>
<%= link_to "Sign up now!", signup_path, class: "btn btn-large btn-primary" %>
</div>
<br/>
<%= link_to image_tag("rails.png", alt: "Rails"), 'http://rubyonrails.org/' %>
But then when I include this code:
<div class="span8">
<h3>Micropost Feed</h3>
<%= render 'shared/feed' %>
</div>
it breaks.
Full home.html.erb:
<% if signed_in? %>

Here is my _feed.html.erb:
<% If #feed_items.any? %>
<ol class="microposts">
<%= render partial: 'shared/feed_item', collection: #feed_items %>
</ol>
<%= will_paginate #feed_items %>
<% end %>
And here is my _feed_item.html.erb
<li id="<%= feed_item.id %>">
<%= link_to gravatar_for(feed_item.user), feed_item.user %>
<span class="user">
<%= link_to feed_item.user.name, feed_item.user %>
</span>
<span class="content"><%= feed_item.content %></span>
<span class="timestamp">
Posted <%= time_ago_in_words(feed_item.created_at) %> ago.
</span>
<% if current_user?(feed_item.user) %>
<%= link_to "delete", feed_item, method: delete,
data: { confirm: "You sure?" },
title: feed_item.content %>
<% end %>
</li>
Sorry in advance for my markup, this is my first stack overflow question.
Oh and here is the error I'm getting when I attempt to load my local site:
SyntaxError in Static_pages#home
Showing /rails_projects/sample_appOct20_2013/app/views/shared/_feed.html.erb where line #7 raised:
/rails_projects/sample_appOct20_2013/app/views/shared/_feed.html.erb:7: syntax error, unexpected keyword_ensure, expecting $end
Extracted source (around line #7):
4: </ol>
5: <%= will_paginate #feed_items %>
6: <% end %>
Trace of template inclusion: app/views/shared/_feed.html.erb, app/views/static_pages/home.html.erb
I think its the capital If
should be:
<% if #feed_items.any? %>
<ol class="microposts">
<%= render partial: 'shared/feed_item', collection: #feed_items %>
</ol>
<%= will_paginate #feed_items %>
<% end %>
Since this is the case, it thinks that the <% end %> tag is not needed. It really is needed but 'If' (capitalized) is not the same as 'if'(lowercase).
