This is probably a simple question, I have a form that you put in a comment it redirects to another page upon submit and displays all comments in a list. I am wondering how i can add an erase button to each list item to remove that particular comment. Thank you in advance, <pre><code>db.define_table('discussion', Field('comment', 'text')) def comment(): form = SQLFORM(db.discussion, _class='test1') if form.process().accepted: redirect(URL('comment_results')) return dict(form=form) def comment_results(): items = db(db.discussion.id==db.discussion.id).select() ???? erase = db(db.discussion.id==).delete() ???? ### trying to create an erase button to delete the currently displayed comment ### return dict(items=items, erase=erase) view: <html> <head> <link rel="stylesheet" href="{{=URL('static','css/test.css')}}"> </head> <body> {{for item in items:}} <li>{{=item.id}} Comment = {{=item.comment}}<button id="{{=erase}}">erase</button></li> {{pass}} </body> </html> </code></pre> * Answer * View: <pre><code><html> <head> <link rel="stylesheet" href="{{=URL('static','css/test.css')}}"> </head> <body> {{for item in items:}} {{=item.comment}}<a href="{{=URL('delete', args=item.id)}}"> Delete</a> {{pass}} </body> </html> </code></pre> * I just passed the args to the delete method in the controller * Controller: <pre><code>def delete(): query = db(db.discussion.id==request.args(0)).select().first() ## grabbing comment to be deleted from comment_results remove = db(db.discussion.id==query).delete() if remove: redirect(URL('comment_results')) return dict(remove=remove) </code></pre>

1. COSorry, I was not specific with the fact that I am using web2py. Turns out, all i needed to do was link to a different delete method in my controller. I will edit the question to show what I did.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
