Get the value of <option> from views to the controller

Question

Since 'HTML' do not have the attribute 'name',I am looking for a way to accept the value, which I populated in views, in the controller and assign it a variable name for another use. This is sample of my code:`

enter code here<form action="<%=url_for(:action =>:make_comment) %>">

<fieldset>
<select>
<%@category.each {|x|%>
<option id="label"> <%=x%></option>
 <%}%>
</select>
</fieldset>
<input type="submit" value="submit"/>
</form>`

Answer 1

Are you saying that your html doesn't have a name attribute? If so, why?

The name attribute is what the server will interpret as the "key" for the value that you are sending. I don't know what other way you could try to go about doing this.

Maybe if you paste some code from your controller and your view, I could give a better answer.

Edit: After seeing your edited question, what you want to do is have your select tag with the name attribute, and your option tags have a value attribute with the value you want to send.

Hope this helps.

Answer 2

This example show how you create a select tag:

select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, {})

In this case, you would be able to get (in your controller) the value of the selected option through

params[:post][:person_id]

Is this what you want? Let me know if I misunderstood your question.
