javascript - Pull post image in rails display in div -

i've created js grid , i'm trying pull logo image , display in div data-thumbnail

how add together link pull post images?

<%- model_class = post -%> <div class="spacer spacer-big"></div> <div class="container" style="padding-right:50px;padding-left:50px;"> <div id="grid"> <div class="box"> <div data-thumbnail= "trying post logo here" </div>

i inserted <%=image_tag post.logoimage.url %> between quotation marks i'm still getting error.

fix

you'll need this:

<%= content_tag :div, "", data: { thumbnail: @post.logoimage.url } %>

here's info on content_tag you

this should accompanied next controller action:

#app/controllers/your_controller.rb class yourcontroller < applicationcontroller def action @post = post.first #-> sets post object end end

--

data

the error receive follows:

undefined local variable or method `post'

this means view calling non-existent object (variable) (post). solution create sure post set correctly. , this, need either utilize controller (as per rails' mvc pattern, or set in view:

<% post = post.first %> <%= content_tag :div, "", data: { thumbnail: @post.logoimage.url } %>
