| 2013-09-11 10:56 <marc0s> is there any way to allow multiple tabs opened for the same model? I'm using version 2.6 and customer would like to have multiple party entries opened at once | ||
| 2013-09-11 11:19 <bechamel> marc0s: shift+click does the trick | ||
| 2013-09-11 11:20 <marc0s> bechamel: oh my... :D | ||
| 2013-09-11 11:20 <marc0s> thanks :) | ||
| 2013-09-11 11:21 <marc0s> as my customer will ask, any way to make this the default mode of operation? | ||
| 2013-09-11 11:27 <bechamel> marc0s: not without changing the code | ||
| 2013-09-11 11:28 <marc0s> bechamel: ok, thanks | ||
| 2013-09-11 14:30 <WUD> Is there a way that I can override the init method and set certain properties on a <ModelSQL> class whenever I initialise an instance from the GTK? | ||
| 2013-09-11 14:51 <WUD> cedk: is there a way to call __init__ method on a ModelSQL subclass? | ||
| 2013-09-11 14:52 <motaro> Question: Why when I create a new Employee I have to set the id/code field | ||
| 2013-09-11 14:52 <motaro> ¿Couldn't just use an increment? | ||
| 2013-09-11 14:53 <jeancavallo> WUD: What kind of modifications are you talking about ? | ||
| 2013-09-11 14:54 <WUD> jeancavallo: I just want to set certain properties of a ModelSQL subclass whenever I press the 'New' button on it | ||
| 2013-09-11 14:54 <jeancavallo> WUD: Are you talking about default values ? | ||
| 2013-09-11 14:55 <WUD> yeah, I want something to have a default value | ||
| 2013-09-11 14:55 <jeancavallo> WUD: Then you can define a classmethod named default_<field_name> which returns the default value you want | ||
| 2013-09-11 14:56 <WUD> but I need to access a property on the instance I'm accessing | ||
| 2013-09-11 14:57 <jeancavallo> WUD: But you just created the instance... How was this property set ? | ||
| 2013-09-11 14:58 <WUD> umm, in the initialiser ? It's a M20 field for another class | ||
| 2013-09-11 14:59 <jeancavallo> WUD: So you got an instance of model A with a M2O to a model B and you want to set default values when creating a new B instance from the link ? | ||
| 2013-09-11 15:02 <WUD> My scenario is I have a Model B, which as an M2O to Model A, now this Model B has been subclassed, and I want to set a property on it, whenever it's initialised from Model A's view | ||
| 2013-09-11 15:02 <WUD> that's why I was trying to override the __init__ method and do it from there, do some custom inits | ||
| 2013-09-11 15:12 <jeancavallo> WUD: You can use the context to pass some informations from your model A instance. You can then access it in the default methods of model B through Transaction().context.get(...) | ||
| 2013-09-11 15:12 <WUD> That's the problem, I am setting the context, but my key values aren't showing up when I access the Transaction in Model B | ||
| 2013-09-11 15:20 <jeancavallo> WUD: How are you setting the context ? | ||
| 2013-09-11 15:21 <WUD> jeancavallo: Transaction().set_context({}) | ||
| 2013-09-11 15:22 <WUD> Transaction().set_context({'key': 'value'}) | ||
| 2013-09-11 15:22 <jeancavallo> WUD: You need to use the context parameter un your model A field description | ||
| 2013-09-11 15:23 <jeancavallo> WUD: Something like : my_model_b = fields.Many2One('model_A', 'My Model B', context={'my_key': Eval('my_other_field')}) | ||
| 2013-09-11 15:23 <jeancavallo> WUD: s/model_A/model_B | ||
| 2013-09-11 15:23 <WUD> I tried this and the other one also | ||
| 2013-09-11 15:23 <WUD> But this didn't work either | ||
| 2013-09-11 15:23 <WUD> jeancavallo: | ||
| 2013-09-11 15:24 <WUD> I can't access this field on the other model | ||
| 2013-09-11 15:24 <jeancavallo> WUD: Then it looks like a bug. Could you provide your code (in a pastebin) ? | ||
| 2013-09-11 15:49 <WUD> jeancavallo: http://pastebin.com/BnErxHzW | ||
| 2013-09-11 15:49 <WUD> I'm setting the context inside a function field | ||
| 2013-09-11 15:50 <jeancavallo> WUD: I assume the "lines" field is defined in Model A. In this case, your Eval statement is wrong, it should be Eval('field_name') | ||
| 2013-09-11 15:52 <jeancavallo> WUD: And field_name should be presented in your form view | ||
| 2013-09-11 15:52 <WUD> Setting the transaction in a function field works? | ||
| 2013-09-11 15:55 <jeancavallo> WUD: It should. but be careful that Fuction fields are readonly (except if you define the 'setter' parameter) | ||
| 2013-09-11 15:55 <WUD> I have a setter parameter | ||
| 2013-09-11 15:56 <jeancavallo> WUD: Ok. Is your default called properly ? | ||
| 2013-09-11 15:56 <WUD> Yeah, well now I can see the key of the Transaction appearing in my default, but It doesn't have a value | ||
| 2013-09-11 15:57 <WUD> Transaction context | ||
| 2013-09-11 15:58 <jeancavallo> WUD: Nice. So that means the Eval returns nothing. Is the field you are trying to get displayed (and set) in your form view ? | ||
| 2013-09-11 15:58 <WUD> No, it's a M20 field | ||
| 2013-09-11 15:58 <jvblasco> contexts are a thing that i haven't found many documentation about and i think are really important | ||
| 2013-09-11 15:59 <jeancavallo> jvblasco: it is... And you're so right | ||
| 2013-09-11 16:00 <WUD> jeancavallo: It's not in my view because it's just a M2O field | ||
| 2013-09-11 16:00 <jeancavallo> WUD: Let's call the field you want to access in your default "foo" | ||
| 2013-09-11 16:00 <WUD> okay | ||
| 2013-09-11 16:00 <jeancavallo> WUD: your Eval should be : Eval('foo') | ||
| 2013-09-11 16:00 <jeancavallo> WUD: right ? | ||
| 2013-09-11 16:00 <WUD> yeah, that's what I have | ||
| 2013-09-11 16:00 <WUD> Eval('name of field in my model') | ||
| 2013-09-11 16:01 <jvblasco> does anyone know a place to check some documentation about contexts in tryton? I was able to understand them in other plataforms (eg. magento) but i don't really understand the contexts here as they are associated to the transaction object, u can have multiple contexts and that kind of stuff | ||
| 2013-09-11 16:01 <jeancavallo> WUD: Ok. Try Eval('foo', 10) | ||
| 2013-09-11 16:01 <WUD> jeancavallo: a minute | ||
| 2013-09-11 16:01 <jvblasco> WUD: was the code in the paste bin from model A or B? | ||
| 2013-09-11 16:02 <jvblasco> WUD: cause u are talking about a m2o relation and i see in the code a o2m relation | ||
| 2013-09-11 16:02 <WUD> the field inside the eval is a m2o | ||
| 2013-09-11 16:02 <WUD> the field i'm writing is o2m | ||
| 2013-09-11 16:03 <WUD> I did the Eval('foo', 10) thing, it's still an empty string in my context | ||
| 2013-09-11 16:03 <jeancavallo> WUD: Just to be sure, model A is the model of your M2O or the model in which your "lines" field is defined ? | ||
| 2013-09-11 16:03 <jvblasco> WUD: Not sure about this, but as far as i know, Transaction() supports multiple contexts, take care with the context is using | ||
| 2013-09-11 16:04 <jvblasco> WUD: if u did something like Transaction().set_user(0) in your code, the context changes and may not have the values used in the function field | ||
| 2013-09-11 16:04 <jeancavallo> jvblasco: WUD: That should not be a problem, we're talking about a client call so no risk of multiple context from the framework | ||
| 2013-09-11 16:05 <jvblasco> jeancavallo: then i really need to study/read some documentation about contexts | ||
| 2013-09-11 16:05 <WUD> jeancavallo: showing you a better code example | ||
| 2013-09-11 16:06 <jvblasco> WUD: jeancavallo: anyway i'm using tryton in the backside. I'm working very little with the client. All i do there is extend some views to add some fields. | ||
| 2013-09-11 16:07 <jvblasco> i cannot help much more, my knowledge in tryton is still very limited xP, sorry about that. | ||
| 2013-09-11 16:07 <WUD> http://pastebin.com/mr3gmMwd | ||
| 2013-09-11 16:07 <WUD> jeancavallo: | ||
| 2013-09-11 16:10 <jeancavallo> WUD: Which field are you trying to default ? Another field in Model B ? | ||
| 2013-09-11 16:10 <WUD> yeah | ||
| 2013-09-11 16:10 <WUD> yeah jeancavallo | ||
| 2013-09-11 16:11 <jeancavallo> WUD: And otherField is properly displayed along with myField ? | ||
| 2013-09-11 16:11 <WUD> otherField isn't shown in the view | ||
| 2013-09-11 16:11 <WUD> does it need to be in the view for Eval to work? | ||
| 2013-09-11 16:11 <jeancavallo> WUD: That's it | ||
| 2013-09-11 16:11 <jeancavallo> WUD: either that or you can add depends=['otherField'] in myField definition | ||
| 2013-09-11 16:12 <WUD> then I won't have to put it in my view? | ||
| 2013-09-11 16:12 <WUD> jeancavallo: like so? http://pastebin.com/C2vHjf1Q | ||
| 2013-09-11 16:13 <jeancavallo> should not be necessary | ||
| 2013-09-11 16:13 <jeancavallo> WUD: depends inside the O2M definition, not the Function | ||
| 2013-09-11 16:13 <WUD> Okay | ||
| 2013-09-11 16:22 <WUD> thanks jeancavallo It's finally working | ||
| 2013-09-11 16:22 <jeancavallo> WUD: Nice :) | ||

| 2013-09-11 16:32 <WUD> jeancavallo: i'm getting an error 'you try to read records that don't exist', what's the cause of something like this? I did all that so that I could set a field in my ModelB, which I thought was causing it | ||
| 2013-09-11 16:33 <jeancavallo> WUD: That usually means that you tried to read an id that does not exist. | ||
| 2013-09-11 16:34 <WUD> but the field I just tried to set is the one that causes this problem | ||
| 2013-09-11 16:35 <WUD> there's also a document type in the same error message | ||
| 2013-09-11 16:35 <WUD> which says party.party | ||
| 2013-09-11 16:37 <jeancavallo> WUD: That's not enough information... Only idea I can have is that your default field returns something weird | ||
