|
27 To debug your RQL statements, it can be useful to enable a verbose output: |
|
28 |
|
29 .. sourcecode:: python |
|
30 |
|
31 from cubicweb import server |
|
32 server.set_debug(server.DBG_RQL|server.DBG_SQL|server.DBG_ALL) |
|
33 |
|
34 .. autofunction:: cubicweb.server.set_debug |
|
35 |
|
36 Another example showing how to debug hooks at a specific code site: |
|
37 |
|
38 .. sourcecode:: python |
|
39 |
|
40 from cubicweb.server import debugged, DBG_HOOKS |
|
41 with debugged(DBG_HOOKS): |
|
42 person.cw_set(works_for=company) |
