AttributeError: 'str' object has no attribute 'application'

[Johann Spies]

I have the following function in a module.  When I comment out the 'links' it works without a problem, but with the links active I get the error in the subject line:

def artikels(query = None):
    db = current.db
    if not query:
        query = db.akb_articles.id > 0
                           
    links = [lambda row: A(T('show article'), _href = URL(r = request, c = 'default',
                                                      f = 'show_akb_article',
                                                      args = row.id
                                                      ))]
    fields = [db.akb_articles.title, db.akb_articles.primaryauthor,
              db.akb_articles.authors,
              db.akb_articles.journal, db.akb_articles.pubyear, db.akb_articles.url]    
   
   
    form = SQLFORM.grid(query,
                        fields = fields,
                        orderby = db.akb_articles.title,
                        maxtextlength = 90,
                        editable = False, deletable = False,
                        details = False,
                        searchable = False,
                        links = links,
                        ui = 'jquery-ui')
    return form

Why?

Your links function calls URL with r=request -- is request defined as a string somewhere in the module before that function?

There is no "r" parameter for URL. Not sure what you are trying to pass. You already specify the controller and function.

Yes, there is an "r" argument to URL -- it takes a request object and reads the current application, controller, and function from it if not provided explicitly.

So there is. That is handy. Not mentioned in the book!

In most cases, it's not necessary -- when you exclude "r", it defaults to current.request.

Should that not be current.request?

Yes!  Thanks Cliff.  Well spotted.
