+\f0\fs26 \cf0 \cb2 [09:02] <tud> Do propel has the option to automatically join tables with their foreign key? I have some tables and would like to join them all with their foreign keys\
+[09:05] <\cf3 Jarda\cf0 > tud: you can do FooQuery::create()->joinWith('Foo.Bar')->find()\
+[09:06] <Jarda> didn't really get what you mean\
+[09:06] <tud> Is "Bar" the foreign key in your example?\
+[09:07] <Jarda> yeah\
+[09:07] <tud> thanks\
+[09:08] <tud> dorn here xD\
+[09:08] <tud> the problem is we need 2 join a lot of tables dynamicly\
+[09:08] <tud> is there a best pratice\
+[09:09] <tud> for example we get via get params ColumnA,TableA and ColumnB,TableB -> now we need 2 join those 2 tables and select the 2 coulmns\
+[09:09] <tud> this needs 2 be done dynamicly\
+[09:09] <Jarda> hmm.. ok\
+[09:09] <tud> any ideas?\
+[09:09] <Jarda> well\
+[09:10] <Jarda> you could in your FooQuery class write a public function joinByParameters(array $params) \{\'a0foreach ($params as $parm) \{ $this->joinWith(...); \} return $this; \}\
+[09:10] <Jarda> or something like that\
+[09:10] <Jarda> depends on the specific use case\
+[09:12] <tud> so the best way is 2 use joinwith where u give the column u wanna join on?\
+[09:12] <Jarda> yeah, or actually it's the foreign key name you give as parameter\
+[09:13] <Jarda> <foreign-key foreignTable="bar"><reference local="bar_id" foreign="id" /></foreign-key> and then you use ->joinWith('Foo.Bar');\
+[09:13] <tud> what happens if u have done smith like this: tbl1->join with(tbl2.column) ->joinwith(tbl3.column)->join with(.... does that work?#\
+[09:13] <Jarda> you can have multiple joins, yes\
+[09:14] <tud> and he automatically detects how 2 join it? over multiple tables?\
+[09:14] <Jarda> yes, it should work\
+[09:16] <tud> for example if tbl1.A->tbl2.A and tbl1.B->tbl3.A but we join tbl1->join with(tbl2.A)->join with(tbl3.A) - this will work?\
+[09:17] <Jarda> if the foreign keys are wrintten in the schema, it should work\
+[09:17] <Jarda> try it out\
+[09:18] <tud> k much thx if that works its really amazing work ;-) much thx 4 the help}
