I'm porting an application to Rails 3.
We're an e-commerce site and naturally we send copies of tax invoices by email. We use plain text, so a .text.erb seems logical.
We also display invoices in an area of the user profile, inside <pre></pre> tags. Is there are way I can share a partial between plain text mailer templates, and views in HTML? If I try to render "shared/invoice" inside my HTML ERB template, it says the partial doesn't exist, and that's because it's a .text.erb partial.
What are my options, without duplicating code?
I haven't tried this in Rails 3, but in Rails 2 you could specify the format of the partial. Might be worth giving it a go on Rails 3.
render :partial => "shared/invoice.text.erb"

I am learning Rails 5.0, via a tutorial. Learning how to generate view templates, but the term "template" is never explicitly defined. I've searched in the Rails docs, and they seem to mention the word a lot, but also never really define it explicitly.
I know that views are the HTML, CSS associated with what the user sees. But was wondering what is a template and how is it different than a standard webpage?
I don't have an authoritative answer. But this is really rather simple. RoR lets you generate content dynamically. This means, with one template, you could generate different content (html pages). The final html page generated and served by the server is the webpage endusers see. For example, you could have a template show.html.erb with the following line:
<h> Product <%=#product.name%> </h>
From this template, different webpages for each different #product can be generated with that #product's name, depending on the #product variable, which is provided by the controller.
So templates allow you to dynamically generate content and render them as different html webpages.
Essentially I'm trying to implement a way so that users can edit slim that is stored in the database.
For example they would use the form to create a new page and insert the html for that page in a text field which would be saved in the database. I want to allow them to edit that page in slim. By the way the html stored is slim not plain html.
If I store slim in the database how do I get rails to render the html properly on the client side in production? So in other words would rails automatically do this since the view is being render like so:
views/page/view.html.slim
page.header
page.content
page.footer
or would I have to figure out a way to convert on the fly? I might be making this more complicated then I should but I'm new to this
If I understand you correctly you want to convert the slim to Html and output that in your views.
This is directly from slims doc. This is how it processes slim files and outputs it.
Tilt.new['template.slim'].render(scope)
Slim::Template.new('template.slim', optional_option_hash).render(scope)
Slim::Template.new(optional_option_hash) { source }.render(scope)
so in short
Slim::Template.new(page/view.html.slim).render
put that in a module to make it prettier and I think you're good. You may want to use rails path helper to get the direct link for the view. You may also want to consider figuring out a way to catch the errors in indentation so that your output doesn't bug out in production. Some kind of validation that prevents it from saving if not properly formatted should help.
I am pretty new to Rails. One of the requirement is to have a Filter Panel that would appear along each record list and will be used to filter records based on criteria. What actually I am looking for an HTML based UI of it that will contain input fields along with labels that I would like to pass from Controller. Since I will be using it across views so I don't want to put in a view specific folder. What's the best way to accomplish this?
You can actually render partials from any folder. For example, in users/show.html.erb you can render a partial _info from, say, transactions.
<%= render 'transactions/info' %>
A common thing to do is to put such shared partials into a separate directory with a descriptive name (I use "shared").
<%= render 'shared/filter_panel' %>
you can put them in /views/application/ dir, rails automatically look for partials in this directory
if you use the application directory then you can just do render 'partial' from any view and it will render /views/application/_partial.html.erb
you can also create for e.g. /views/admin/base dir (if you have admin/base_controller.rb) and put your admin namespace partials there
if you have many partials, I recommend you put them into subdirectories
In ActiveAdmin I have setup a small form for sending bulk emails to users. In the form I have the option to parse text using html or markdown. I have two different views and depending on the content type attribute of the email, one of the two is rendered. I pass the #content of the email to the views and in the one I call simple_format #content and in the other - a helper method markdown #content. So the question is - how do I test the email views. Everywhere I see ways to preview emails in the browser, but I want to have some written tests, which I can run along with my full test suit. So far, the only idea I have come up with is to use Capybara and something like:
visit '/mail_view'
expect(find 'a.reset_password').to contain reset_password_path(user)
Is this the way to go or is there another standard?
I am suffering a issue with rails server side validation. Can some one help me out from this?
situation is :
I am creating dynamic for and its elements also dynamic.My application will generate the some HTMl code. Which can we use in any form or blog..
I applying the server side validation. But due to dynamic elements .I am not able to store the last entered value in to the elements. AS we normally does in PHP if user input something wrong we don't put the field empty. So I need to find a mechanism which fills the older values into the elements,If something went wrong.
This is the code into controller which is I'm using to show the form :
render :layout => false,:template=>'buildders/rander_form'
and view of rander_form.html.erb has
<%= render :file=>RAILS_ROOT+'/public/forms/form_'+#form_name+'.html.erb' %>
where #form_name is a dynamic form name(which have HTML code).
Can some one help me?
don't put erb files in public, people can download them by entering the file path in the url
also why not move that code out of the erb template into the controller?
