💡 Hint

Common Mistakes

Including the underscore in the partial name.

Using 'partial:' keyword incorrectly.

Using symbols instead of strings.

In Rails, to render a partial named '_menu.html.erb', you use render 'menu'. This tells Rails to look for the partial with that name.

💡 Hint

Common Mistakes

Using => instead of : inside the hash.

Not wrapping the locals in curly braces.

Using assignment (=) instead of hash syntax.

To pass local variables to a partial, you use the locals option with a hash. The key is the variable name inside the partial, and the value is the data you pass.

Ccollection: @products

Dpartial: 'products', collection: @product

💡 Hint

Common Mistakes

Using plural partial name.

Passing collection without partial.

Mixing singular and plural variable names.

To render a collection of objects with a partial, use render partial: 'product', collection: @products. This renders the partial for each item in the collection.

Fill both blanks to render a partial '_comment.html.erb' for each comment in @comments and pass each comment as a local variable named 'comment'.

Drag options to blanks, or click blank then click option'

A'comment'

B@comments

C'comments'

D@comment

💡 Hint

Common Mistakes

Using plural partial name.

Passing a single comment instead of the collection.

Not matching local variable name with partial.

The partial name should be singular 'comment' and the collection is the array @comments. This renders the partial for each comment and passes it as a local variable.

hard

Fill all three blanks to render a partial '_user.html.erb' for each user in @users, pass each user as 'user', and add a spacer partial '_spacer.html.erb' between each user.

Ruby on Rails

<%= render partial: [1], collection: [2], locals: { user: user }, [3]: 'spacer' %>

Drag options to blanks, or click blank then click option'

A'user'

B@users

Cspacer_template

Dspacer_template_name

💡 Hint

Common Mistakes

Using wrong key for spacer partial.

Using plural partial name.

Not passing the local variable correctly.

Use partial: 'user' for the user partial, collection: @users for the list, and spacer_template: 'spacer' to add the spacer partial between items.
