Hi

Could you please explain the difference between form_for and
form_remote_tag…On which circumstances they are used?

Thanks in advance

form_remote_tag is used for creating a form which will be submitted via
Ajax.

There is actually four types of form commands, in two categories:

Model-Backed Forms (forms based on a activerecord object)

Regular Forms (forms not based on a particular object)

and then there are the Ajax and POST variety of each.

So we have:

  1. remote_form_for (ajax, model-backed) which is used to perform ajax
    actions on a form which is composed of fields relating to a specific
    active record object.

  2. form_for (standard POST, model-backed) which is for performing a
    standard http post on a form which is composed of fields relating to a
    specific active record object.

  3. form_tag (standard POST, not model-backed) which is for performing a
    standard http post on a form which is not model backed and has arbitrary
    input fields.

  4. form_remote_tag (ajax post, not model-backed) which is for performing
    a ajax post on a form which is not model backed and has arbitrary input
    fields.
