im new to zope, but i read the 2 books (not everything but very much). im
developing a tree-like structure that i want to use throughout my project to
store tag-information in it. every node should store some tags, that are
extensible by the users by adding new tags as they tag their content they want
the intension of this tree is supporting the content tagging user with aleady
used tags for this content.
i chose the tree structure because it has some context sensitive advantages for
the class-structure behind it is ready and now i dont know how to proceed with
zope. what i need is a textfield, that is associated with some node of the
tree. the textfield will use the ajax-script to display a dynamicly generated
list of similar words as the user types in his letters. the words that can be
similar should come from the node of some tree, that the textfield is
like when you type a url in the firefox browser it supports you with the urls
that where already used.
and like in firefox, when you enter a new url, it is added to the
already-used-urls-list, i need the same thing with my textfield. so this
textfield is not an add-view or something, because it adds only when the tag is
new to the database. the other times its just about selecting some tag and
associate it with the content.
and in some cases, i want the textfield to only be a selectable one, where the
user isnt allowed to add new tags to the database.
i dont know how to start. :( i read the 2 books up and down and search the
internet sources for hints, but i dont get a clue for sure. i can see some
ways, but i dont know if they are the right ones. i think i will have to
implement a new schema, but then i will have to associate it with the right
node-instance of the right tree... and then my imagination already stops. i
just cant clue the pieces to a whole. if you could give me some hints i would
really appreciate that.
just write me, make a schema, for parent class take this one, give it some
attribute for the treenode, write a widget for it... maybe i will need an
utility?? maybe i can or should use some of the utilities that come with the
vocabulary? u see, i dont have a view on the thing as a whole, just pieces and
i dont know how to glue them together.
