Any guidelines to make this multilingual?

The tutorial is written for the upcoming 1.0.3 release. Currently, you will need the code from SVN.

which the trunk or the branch

Hi,

I am (a newbie) working through the Blog tutorial and am pretty confused over the tags section:

The tags field does not appear in the post form and when I add the appropriate code to try and display a box for users to type tags into I get an exception saying tag is not defined.

I've been back over the instructions a few times now and think I'm missing something silly… can anyone point me in the right direction?

If you need more details let me know.

Thanks

Mungo

Which version are you using? The tutorial is for 1.0.3.

Mungo · March 5, 2009, 5:48pm

Hi Qiang,

Wow, quick reply! I am using version 1.0.3

Should there be code in protected/views/post/_form.php for the tags? As there is nothing there…

Cheers

Mungo

p.s. great work, am enjoying everything so far!

qiang · March 5, 2009, 5:51pm

It should have _form.php…

Mungo · March 5, 2009, 5:56pm

yes, the file is there and contains:

<div class="simple">


<?php echo CHtml::activeLabelEx($post,'title'); ?>


<?php echo CHtml::activeTextField($post,'title',array('size'=>60,'maxlength'=>128)); ?>


</div>


<div class="simple">


<?php echo CHtml::activeLabelEx($post,'content'); ?>


<?php echo CHtml::activeTextArea($post,'content',array('rows'=>6, 'cols'=>50)); ?>


</div>


<div class="simple">


<?php echo CHtml::activeLabelEx($post,'contentDisplay'); ?>


<?php echo CHtml::activeTextArea($post,'contentDisplay',array('rows'=>6, 'cols'=>50)); ?>


</div>


<div class="simple">


<?php echo CHtml::activeLabelEx($post,'status'); ?>


<?php echo CHtml::activeTextField($post,'status'); ?>


</div>


<div class="simple">


<?php echo CHtml::activeLabelEx($post,'createTime'); ?>


<?php echo CHtml::activeTextField($post,'createTime'); ?>


</div>


<div class="simple">


<?php echo CHtml::activeLabelEx($post,'updateTime'); ?>


<?php echo CHtml::activeTextField($post,'updateTime'); ?>


</div>


<div class="simple">


<?php echo CHtml::activeLabelEx($post,'commentCount'); ?>


<?php echo CHtml::activeTextField($post,'commentCount'); ?>


</div>


<div class="simple">


<?php echo CHtml::activeLabelEx($post,'authorId'); ?>


<?php echo CHtml::activeTextField($post,'authorId'); ?>


</div>

When I add in:

<div class="row">


<?php echo CHtml::activeLabel($post,'tag'); ?>


<?php echo CHtml::activeTextField($post,'tag',array('size'=>65)); ?>


<p class="hint">


Separate different tags with commas.


</p>


</div>

I get the exception that says:

Property "Post.tag" is not defined.

I've also tried this with tags, Tag and Tags

Does this help clarify my problem?

Cheers

It means the Post table in your database doesn't have the 'tags' column. It shouldn't be because the schema included in the blog demo does have this column.

Mungo · March 5, 2009, 6:05pm

OK, I understand that!

So, next question, how do I get the field to appear and create the relation between the Post table and the Tag table?

I have implemented:

	/**


	 * @return array relational rules.


	 */


	public function relations()


	{


		return array(


			'author'=>array(self::BELONGS_TO, 'User', 'authorId'),


			'comments'=>array(self::HAS_MANY, 'Comment', 'postId',


				'order'=>'??.createTime'),


			'tagFilter'=>array(self::MANY_MANY, 'Tag', 'PostTag(postId, tagId)',


				'together'=>true,


				'joinType'=>'INNER JOIN',


				'condition'=>'??.name=:tag'),


		);


	}

Is there something else I should be doing?

Thanks again for all your help, much appreciated

Mungo

If your Post table already has 'tags' column, you just need to use $post->tags to access it.

If it doesn't, you can define 'tags' relation as follows:

'tags'=>array(self::MANY_MANY, 'Tag', 'PostTag(postId, tagId)')

And then $post->tags will give you an array of Tag objects.

Mungo · March 5, 2009, 6:44pm

Ahhh… got it! That helped - thank you

My silly error was that I had not updated the database to the new schema. (I got half way through the tutorial when the update to 1.0.3 came out!)

While my immediate problem is resolved - I am still a little confused - why have a tags field in the Post table when there is a relation to Tags there already? Is it not possible to create a field that reflects that relation?

Thanks again

Mungo

qiang · March 5, 2009, 6:52pm

That's for speed and convenience. When we display the post list, we want to be fast without the need to join two tables.

Mungo · March 5, 2009, 7:18pm

Interesting!

I guess this is an unusual scenario as the list of tags associated with a post needs to be editable and therefore any of the other form elements are not suitable. Unless there was some kind of dynamic select perhaps.

I don't have the time to look into this at the moment (deadlines looming) but I wonder if an interface similar to the Add Bookmark to Delicious would be a good way to manage tags.

Anyway - problem solved - thank you again for all your help
