mysql - CakePHP sub query SQL in HABTM relation -


I want to match the related products to the tags and sort order the most.

The relationship between the HABT model product and the tag 

  in the class product AppModel {//. Var is $ and bellongtaomany = array ("tag"); // ..}

and in contrast to the tag model. Includes - The table name is "products_tags". Examples of products $ $ include products [0] ['tags'] = array ('touch')

Ex.sample for 

  , 'Phone', '3g', 'apples'); // iPhone $ products [1] ['Tag'] = array ('phone', '3G', 'BB'); //bb $ products [2] ['tag'] = array ('touch', '3g', 'apple'); // ipad $ products [3] ['tag'] = array ('3G', 'air card'); // 3G Air Card

In this sample, the highest priority relates to the iPhone sort.

  1. The iPad (found in 3 tags)
  3. Air Force (only 1 match)

How to get a sub-query by using the cake method model: 

  ID as SELECT DISTINCT (product_id), leave the same tag count as / / sub-query * / select COUNT (*) tag tags as Product_tags on ProductTag (Tag .id = ProductTag.tag_id) WHERE product_id = ID and tag name ('touch', 'phone', '3g', 'apples')) Priority / * This is what tags as tags from / Tag as add (tag id = ProductTag.tag_id) tag. Order IN ('Touch', 'Phone', '3G', 'Apple') Priority Order by DESC

What exactly do I need to return the SQL query but I want CakePHP AppModel-> find () method can not find the way to parse the parameter.

If this SQL result does not use endorsement (assuming that the related product in the normal webpage 3-5 entries), why do not you use this complex SQL?

Then use the $ -> query ($ sql)

The sample code will be: 

  Create function related product () Class Product AppModel {//. Increases Var $ ANDBelongsToMany = array ("tag"); // .. function related product ($ parameter) {$ sql = "select ..... ou .... $ parameter ..."; Return $ $ - $ ($ sql) query; }}

Then you can use it in the controller by 

  $ this-> product-> related products ($ some_permatrums);

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
