Error when adding class to a form

Question

I am running into an error I cant figure out, because it works with another form. I am trying to add a class to a form - it looks like this:

<%= form_for([@post, @post.comments.build]), html: {class: 'form-horizontal'} do |f| %>

but this throws an error:

syntax error, unexpected tLABEL ..., @post.comments.build]), html: {class: 'form-horizontal'} d...

syntax error, unexpected keyword_do_block, expecting keyword_end

If I delete the html: ... the form works (but looks shitty).

This one works (for some reason): <%= form_for @post, html: {class: 'form-horizontal'} do |f| %>

It is probably easy to fix, but since I am new to programming - I just dont get it ;)

Thanks in advance!

The reason you are getting this error is because you have closing parenthesis ) at the wrong place for the form_for helper.

Please try:

<%= form_for([@post, @post.comments.build], html: {class: 'form-horizontal'}) do |f| %>

Another option is to add a space after form_for so that ([@post, @post.comments.build]) and html: {class: 'form-horizontal'} become parameters to form_for

<%= form_for ([@post, @post.comments.build]), html: {class: 'form-horizontal'} do |f| %>

I think you need to include the options hash (even if it is empty) before the html hash:

<%= form_for([@post, @post.comments.build]), {}, {class: 'form-horizontal'} do |f| %>

I think you are really close, but i think this might work:

<%= form_for([@post, @comments]), :html => {class: 'form-horizontal'} do |f| %>

I got that from this question Multiple parameters for form_for()
