问题 I have looked into all threads I could find about this Topic, but nothing solves my Problem.

In my Form I can select the employees, but when I want to save the data he only save the 'created' and 'modified' entry and not the keys. The employee has an string id which is CHAR(36).

问题 So, I have a form in CakePhp using it's Formhelper. There are two associated models in this form: Booking & Guest. The database tables seem to be setup correctly since the page populates the values accurately enough through the associations in the model. When saving my form data, the Booking information saves but not the Guest information. I've simplified the code in the snippets below. Any ideas what I'm doing wrong? Model class Booking extends AppModel { public $name = "Booking"; /

问题 I feel pretty darn dumb for asking this question but I'm baffled, probably because I'm slightly intimidated with cakePHP(new to it, and not very comfortable),but its merits are practically forcing me to use it. So please if you could help, I appreciate it : My problem is with understanding how Model association works. After going through all the section about associations here I am still struggling and actually am not quite sure whether either my database design is flawed, or the associations

I tried this with the following in my Fight model: <?php class Fight extends AppModel { public $name = 'Fight'; public $hasOne =

问题 I have several fields in some of my database tables that my CakePHP models never need to retrieve. Is there some way to set a default set of fields to fetch at the model level? For instance I retrieve some data from a third party designed database that has 50 fields per table, I use 5. I know I can set limits on fields at the time of the find() query and at the time of any associations between models, but I was wondering if there was a model-level approach. 回答1: CakePHP does not offer what

问题 Does anyone knows how to get table name from model name? Also I want to get all column names and its types of that model/table name. Is it possible to get such details of given model name? Thanks. 回答1: Table Name To get the table, see $this->Model->table Or check the model for the class variable $useTable . If that's undefined, then you can infer it from the name of the model: $tableName = Inflector::tableize($this->Model->alias); See the Inflector documentation for similarly useful methods.

问题 I have two tables with field username in both. How i can specify field name for both local and foreign table? I want CakePHP will do something like ON (`T1`.`username` = `T2`.`username`)` in result. Without any changes tables will be joined with following condition: ON (`T1`.`id` = `T2`.`t1_id`)` Setting 'foreign_key' = 'username' property is not enough because it will produce query like this: ON (`t1`.`id` = `t2`.`username`)` I have two solutions.
