sql - DB Evolution in Play Framework 2.0 -


On Play 1.0, when we change a variable type or for example @OneToMany change @ManyToMany to model play Make changes automatically, but with the 2.0 development script drop-down database. What is a way to apply the changes without leaving DB to Play 2.0?

Yes, one way. You need to disable the automatic reconstruction of the file 1.sql and start writing your own evolutions with ALTERS instead of CREATES - them 2.SQL , 3.sql etc.

In practice it means that, if you are working with a single database then you can also ... Manage the database tables and columns using your favorite DB GUI Evolutions Only when you are unable to use the GUI (host external connection is not allowed and do not have any GUI) or when you are planning to run multiple instances of the application on different databases, otherwise the GUI can be used. Yoga manually typing will be manually more complex.

Tip: Sometimes, if I'm not sure if I have added all necessary relationships and barriers to my manual evolution, then I'm removing this Git Controlled Folder!) And with the Abine Plugin Turning the app on and saving the proposed 1.sql , but I am not implementing changes later on using GIT, I am changing my evolution and saved auto-generated savedI'm comparing the Hail and would like to make to convert ALTERS statement. There is no better option for managing changes without using 3-rd Part software.

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
