Collection select options

I want to set a default on a collection select. There must be a way to
do this, but how?

:default => “kdjng” (?)

<%= collection_select(:category, :id, @categories, :id, :name,
{},{:size=>10}) %>
will have the value of @category selected
so you can set the default value to @category and then use the
collection select.

This was the method I used as I had to make different categories as
default selected one for different users.There might be some better ways
too.Eager to know them too.

Thanks for your response.

<%= f.collection_select :brand, [‘Brand 1’, ‘Brand 2’, ‘Brand 3’, ‘Brand 4’], :to_s, :to_s %>

The above is the syntax I’m currently using. In theory, the default
brand would be Brand 1, correct? So when a form containing this
collection gets submitted (without amending the collection), Brand 1 is
parsed as the one selected. At least, that’s what I’m looking for.

If you want to have a default selected value then you can use select_tag

<%= select_tag :brand, options_for_select([‘Brand 1’, ‘Brand 2’, ‘Brand
3’, ‘Brand 4’], “Brand 2”) %>

You had used this
<%= f.collection_select :brand, [‘Brand 1’, ‘Brand 2’, ‘Brand 3’, ‘Brand
4’], :to_s, :to_s %>

in case if the form f object is for article then u can use

<%= select_tag ‘article[brand]’, options_for_select([‘Brand 1’, ‘Brand
2’, ‘Brand 3’, ‘Brand 4’], “Brand 2”) %>

Hope this helps.
