Pass variable to partial(rails 4)

Question

I have a partial _album.html.erb and it has a variable "album" I have a collection @albums . For each in the collection I want to render the partial. But I don't use the option "collection:" because I want to put each one in different position. Here is my code:

<% @albums.each do | f | %>
     ..........
    <td>
           <%= render partial: "album", locals: {"album" f} %>
      .........
<% end %>

This code returns a SyntaxError. I don't know why this happens.

Actually it will be very helpful if you posted logs with Error — Alexander Kireyev

You haven't any divider between "album" and f, so try locals: {album: f} or :album => f

I have a space there . It's my phone's problem. But Thanks

You can't use space, it's a hash. Use => or : ad I suggest.

Sorry, I misunderstand you. I have ":" Between album and f . And have a space between : and f.

Ok, got it. Perhaps then, in partial are you using @album? Cause this location variable will be just album. Use this name instead, and return it in other calls as local.

I use it as album.title. So it just local variable not instance variable .

Locals

Further to zishe's correct answer, you'll need to look up on how to set the syntax for partial local variables:

<%= render partial: "form", locals: {zone: @zone} %>

Rails basically sends a hash of key: value pairs, which means the syntax has to be like this:

locals: {key: value, "key" => value}

You have to remember Rails is basically just a collection of files & classes, which means anything you do has to conform to the ways in which Ruby allows you to assign & pass data, a hash being one of the main ways

I had this problem and I tried with locals: {..} but it didn't work.

You can try this that worked for me:

 <%= render partial: "form", zone: @zone %>
