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.
