<pre>''1.0''
Initial release
----
''2.0''
This release has major changes to both [[Tag|Tag Class]] and [[Taggable|Taggable Class]], reflecting significant and important lessons that [[the author|AdamCrossland]] learned about [[Google AppEngine]].  Specifically, this release's changes should substantially improve the performance of any code that uses tags.
*[[Tag|Tag Class]] entities are now stored with a custom key_name that allows them to be much-more-quickly retrieved from the data store.
*The [[Tag|Tag Class]] has been rewritten to breakdown Tag/Taggable interactions in to a series of simple, atomic transactions.
*[[Tag|Tag Class]] has a new property, [[tagged_count|Tag tagged_count Property]], that records the number of Taggable entities in its [[tagged|Tag tagged Property]] property.
*Two new methods, [[get_tags_by_frequency|Tag get_tags_by_frequency Method]] and [[popular_tags|Tag popular_tags Method]], provide access to lists of [[Tags|Tag Class]] based on the number of [[Taggable|Taggable Class]] entities to which they refer.
*A new method, [[get_tags_by_name|Tag get_tags_by_name Method]], provides lists of tags in alphabetical order.
*The [[Taggable|Taggable Class]] class has been greatly simplified.  Multiple methods for getting and setting tags have been replaced with a single property, [[tags|Taggable tags Property]], that handles both getting and setting operations.
*A full suite of automated unit tests for both classes has been created.</pre>

<div title="Converting from 1.0 to 2.0" modifier="AdamCrossland" created="200812051535" modified="200812051536" changecount="2">
<pre>Because the Tag records are stored and queried slightly differently (yet much-more efficiently) in //Taggable-mixin 2.0//, an existing application will have to go through a process of converting all of its existing tags.

For AdamCBlog, the application from which //Taggable-mixin// is extracted, I added a new RequestHandler called UpdateTag:
{{{
class UpdateTag(RequestHandler):
    def get(self):
        from taggable import Tag
        tag_name = self.request.get('tag')
        tag = db.Query(Tag).filter('tag =', tag_name).fetch(1)[0]
        if tag is not None:
            new_tag = Tag.get_or_create(tag_name)
            for each_tagged in tag.tagged:
                new_tag.add_tagged(each_tagged)
        tag.delete()
    
        self.redirect('/')
}}}

Then, I made the request /~UpdateTag?tag=//inserttaghere// for each Tag in the datastore.  Yes, it is laborious.

Why not just create a RequestHandler that cycled through all of the tags automatically, converting them as it went?  I tried that, but there is too much processing involved; the request uses up its time quota and is killed before it can finish.</pre>

<pre>Here's a step-by-step guide to adding ''Taggable'' to your [[Google AppEngine]] application.  This presents the simplest, most straightforward path to integrating ''Taggable'' as as such, it does not cover all of the options that are available.  

All of the code examples are modified extracts from the blogging software for which I originally created ''Taggable.''  //''These examples do not represent what the author considers to be complete and secure code; please make sure that you are familiar with best practices for building secure web applications before creating a web application.  The author of this document and the accompanying code bears no responsibility whatsoever for any losses or damages that you incur as a result of failing to take the appropriate steps to create a stable, secure, well-written web application.''//

*Copy [[taggable.py]] to your application directory.
*Import [[taggable.py]] into the python file that defines the Model that you want to make taggable:
{{{
from taggable import Taggable
}}}
*Add //Taggable// to the list of classes from which your Model class inherits.  Taggable -- and any other mixin classes -- should come before db.Model:
{{{
class Post(Taggable, db.Model):
}}}
*Add code to your Model's //init// method to call Taggable's //init// method.  If your Model class does not already override //init//, it will have to, and you will have to explicitly call the //init// method of any other superclass -- such as db.Model:
{{{
    def __init__(self, parent=None, key_name=None, app=None, **entity_values):
        db.Model.__init__(self, parent, key_name, app, **entity_values)
        Taggable.__init__(self)
}}}
*Add code to your template to express the tagging information:
{{{
{% if post.tags %}
    &lt;div class=&quot;posttags&quot;&gt;tags:&amp;nbsp;
        {% for each_tag in post.tags %}
            &lt;a href=&quot;/searchbytag?tag={{ each_tag.tag|escape }}&quot;&gt;{{ each_tag.tag }}&lt;/a&gt;{% if forloop.last %}{% else %}, {% endif %}
        {% endfor %}
    &lt;/div&gt;
{% endif %}
}}}
or
{{{
&lt;tr&gt;
    &lt;td&gt;Tags:&lt;/td&gt;
    &lt;td&gt;
        &lt;input type=&quot;TEXT&quot; name=&quot;tags&quot; size=&quot;106&quot; value=&quot;{% if post %}{{ post.tags_string }}{% endif %}&quot; /&gt;
    &lt;/td&gt;
&lt;/tr&gt;
}}}
*In any RequestHandler method that updates a Model object that has tags associated with it,  assign any new value to the ''Taggable'' object's [[tags|TaggableTagsProperty]]:
{{{
class EditPost(SmartHandler.SmartHandler):
    def post(self):
        postid = self.request.get('id')
        post = Post.get(postid)
        post.title = self.request.get('title')
        post.body = self.request.get('body')
        post.edited = datetime.datetime.now()
        post.tags = self.request.get('tags')
        post.put()
        .
        . do whatever else you need to do in your handler...
        .

The //add_tagged// method adds the [[Key|Key Class]] passed in to the Tag's [[tagged|Tag tagged Property]] collection and increments the [[tagged_count|Tag tagged_count Property]].  The operations are performed inside a transaction to ensure data intergity.

Comments:
This method removes from memcache any objects that have been cached by other [[Tag|Tag Class]] methods.

<pre>The //Taggable// class can be mixed-in to any other Python class that inherits from //db.Model// in order to associate [[Tags|Tag Definition]] with that model.

Usually, a Post can have [[Tags|Tag Definition]] added to it in order to provide easily-digested information to the reader about the content.

It has two properties:
*[[tags|Taggable tags Property]]
*[[tag_separator|Taggable tag_separator Property]]

and one method:
*[[tags_string|Taggable tags_string Method]]

Notes:
*Notice that [[Taggable|Taggable Class]] is placed before db.Model in the inheritance list.  While this is not strictly required for //Taggable-mixin// to function correctly, it //is// required for other mixin classes, and it is generally a good practice.

<pre>The //tag_separator// property is the string that is used to separate individual tags in a string representation of a list of tags.

It is also used by the [[tags_string|TaggableTagsStringMethod]] method to construct a string representation of the tags for a [[Taggable|TaggableClass]] object.

*By default, it is set to a comma (','), but it can be programatically-set to whatever value the developer desires
*It is probably best to avoid using whitespace characters, as that would prevent users from entering multi-word tags
*Custom separator values can be set at different levels.
**To set one value for all [[Taggable|TaggableClass]] objects, modify the //init// method in the //Taggable// class in the taggable.py file:
{{{
class Taggable:
     def __init__(self):
        self.tag_separator = &quot;;&quot; # Made it semi-colon instead of comma
}}}
**To set one value for all instances of a particular [[Taggable|TaggableClass]] class, modify the //init// method of that class:
{{{
class Post(Taggable, db.Model):
    body = db.TextProperty(required = True)
    title = db.StringProperty()
    added = db.DateTimeProperty(auto_now_add=True)
    edited = db.DateTimeProperty()
            
    def __init__(self, parent=None, key_name=None, app=None, **entity_values):
        db.Model.__init__(self, parent, key_name, app, **entity_values)
        Taggable.__init__(self)
        self.tag_separator = &quot;;&quot; # Made it semi-colon instead of comma        
}}}
**To set a value for one particular instance of a [[Taggable|TaggableClass]] class, set the value after creating the instance:
{{{
newpost = Post(title = self.request.get('title'), body = self.request.get('body'))
newpost.tag_separator = &quot;;&quot; # Made it semi-colon instead of comma
newpost.set_tags_from_string(&quot;foo; bar; bletch; this is a tag; tags rule&quot;     
}}}</pre>

<pre>The a [[Taggable|Taggable Class]] class's //tags// property is used to assign [[Tags|Tag Class]] to the [[Taggable|Taggable Class]] instance or retrieve a //list// of those already assigned.

Assignment Example:
{{{
class Post(Taggable, db.Model):
    index = db.IntegerProperty(required=True, default=0)
    body = db.TextProperty(required = True)
    title = db.StringProperty()
    added = db.DateTimeProperty(auto_now_add=True)
    added_month = db.IntegerProperty()
    added_year = db.IntegerProperty()
    edited = db.DateTimeProperty()
        
    def __init__(self, parent=None, key_name=None, app=None, **entity_values):
        db.Model.__init__(self, parent, key_name, app, **entity_values)
        Taggable.__init__(self)

    @classmethod
    def new_post(cls, new_title=None, new_body=None, new_tags=[]):
        if new_title is not None and new_body is not None:
            
            new_post = Post(title = new_title, body = new_body)
            new_post.put()
        
            new_post.tags = new_tags
            new_post.save()
        else:
            raise Exception(&quot;Must supply both new_title and new_body when creating a new Post.&quot;)
}}}
