| 2011-12-05 00:07 <cjbarnes18> cedk: re issue2313, I think this issue is really 2, 1st concern is that the error is not clear. I had to mute each field to find that time was the problem. | ||
| 2011-12-05 00:08 <cjbarnes18> cedk: 2nd is the obvious missing widget. | ||
| 2011-12-05 00:08 <cjbarnes18> I dont have a use case for this I am simply trying everything out. | ||
| 2011-12-05 00:09 <cjbarnes18> cedk: I have found more missing on tree views. | ||
| 2011-12-05 00:09 <cedk> cjbarnes18: yes of course, all fields are not displayable in all views | ||
| 2011-12-05 00:11 <cjbarnes18> would a not_supported_in_view+exception be in order do you think? | ||
| 2011-12-05 00:31 <cedk> cjbarnes18: why not | ||
| 2011-12-05 00:34 <cjbarnes18> cedk: ok will add this to the list, Am happy to attempt both if thats OK, | ||
| 2011-12-05 13:50 <grasbauer> hi | ||
| 2011-12-05 13:56 <grasbauer> someone with a shopping cart connected to tryton? how you handle the gross price shown to the client? Mostly in onlineshops there are products with a gross price - not untaxed list_prices .... still thinking about the best way to handle this ... | ||
| 2011-12-05 13:58 <cedk> grasbauer: I think you must store on the product the gross price | ||
| 2011-12-05 13:59 <cedk> grasbauer: and of course you can not use sale module | ||
| 2011-12-05 13:59 <zxq9> Does anyone remember how to place an image into a report from a binary field in the database? | ||
| 2011-12-05 14:00 <grasbauer> zxq9: widget="image" | ||
| 2011-12-05 14:00 <zxq9> Into a report, not view. | ||
| 2011-12-05 14:00 <zxq9> Like in an ODT | ||
| 2011-12-05 14:01 <zxq9> I'm trying to follow the Relatorio and Genshi docs, but I'm getting problems. | ||
| 2011-12-05 14:02 <zxq9> Like insert Frame with "image: (model.fieldname, 'image/jpeg')" and getting errors like "'buffer' object has no attribute 'seek'" after opendocument.py tries bistream.seek(0) | ||
| 2011-12-05 14:03 <cedk> zxq9: must convert it into str | ||
| 2011-12-05 14:04 <zxq9> image: ('model.fieldname', 'image/jpeg') ? Because that doesn't work, either. I then get "'str' object has no attribute 'seek'" | ||
| 2011-12-05 14:05 <cedk> zxq9: oops, yes you must use a StringIO | ||
| 2011-12-05 14:07 <grasbauer> zxq9: i did it with a method that creates StringIO.StringIO() from the data | ||
| 2011-12-05 14:09 <zxq9> How did you do that? | ||
| 2011-12-05 14:09 <grasbauer> zxq9: one moment | ||
| 2011-12-05 14:09 <zxq9> You mean define a method in the model that I can call from the ODT which returns the correct ('image', 'mimetype')? | ||
| 2011-12-05 14:10 <grasbauer> zxq9: yes | ||
| 2011-12-05 14:11 <zxq9> I'm not familiar enough with Python data operations to do that without reading an example, I think. | ||
| 2011-12-05 14:13 <cedk> I think we must improve relatorio to work also with str/buffer | ||
| 2011-12-05 14:15 <zxq9> If we could declare mutable variables in Relatorio instead of instance constants that would be very helpful. Arbitrary loops (like a "while" with an arbitrary closing condition) would be very useful too and sort of complete the mini-language. | ||
| 2011-12-05 14:16 <zxq9> At the moment with no mutable variables the only way to create an iterator is to make a list object and list.append(1) and test len(), which is really silly. | ||
| 2011-12-05 14:17 <cedk> http://relatorio.openhex.org/ticket/44 | ||
| 2011-12-05 14:18 <cedk> zxq9: I think it is a bad practice to put code in templates | ||
| 2011-12-05 14:18 <zxq9> cedk: It is, but we are already doing it when we use <for each="foo in bar">. | ||
| 2011-12-05 14:19 <zxq9> cedk: Its a stupid idea to code inside a web page, but that is what people are doing also -- and that's not much different than coding in templates. | ||
| 2011-12-05 14:19 <cedk> zxq9: it is quite different to have a loop and having a full assignation | ||
| 2011-12-05 14:19 <zxq9> cedk: Having conditionals is great, and having for each is great, but it doesn't work when you have set-length forms instead of things like invoice forms that are allowed to grow longer with each item. | ||
| 2011-12-05 14:19 <cedk> zxq9: as you say it is stupid so don't encourage it | ||
| 2011-12-05 14:20 <zxq9> cedk: But its the only way to do things like properly paginate when you have a government form you must fill out which will be rejected if altered -- and it always has 20 rows, but you have 43 people, so you need 3 pages, 20 + 20 + 3. | ||
| 2011-12-05 14:20 <cedk> zxq9: no, as I already told you you must fix it on the report code | ||
| 2011-12-05 14:21 <zxq9> cedk: I know. And I agree. But people have bosses. | ||
| 2011-12-05 14:21 <zxq9> cedk: I have had to finish this ridiculous project, writing in really crazy Relatorio code inside the report documents. | ||
| 2011-12-05 14:22 <zxq9> cedk: But now... now I can make another version, with the code in a module that goes with the report, and demonstrate how that is better. | ||
| 2011-12-05 14:22 <cedk> zxq9: relatorio doesn't have a boss so we do only good practice | ||
| 2011-12-05 14:22 <zxq9> cedk: But without having done all this crazy Relatorio stuff I couldn't have gotten this far to even begin the argument. | ||
| 2011-12-05 14:22 <zxq9> cedk: If you want people with full time employees and money to start showing up you're going to have to be a little more accomodating than that. | ||
| 2011-12-05 14:24 <zxq9> cedk: The same thing with the language thing VS languages with multiple scripts. I tried doing the translation thing, by the way, but calling setLang() doesn't work beyond multiple calls in a document -- so you can't use it per-field for more than a single field (and we had hundreds). | ||
| 2011-12-05 14:24 <cedk> zxq9: I don't care, I don't want to maintain crappy software | ||
| 2011-12-05 14:24 <zxq9> cedk: And the multiple languages was really confusing for the customer, because there are really a lot of fields where you have to write several alphabet types. :-( | ||
| 2011-12-05 14:25 <cedk> zxq9: this is the last time I said, you must *write code in report parser* | ||
| 2011-12-05 14:25 <zxq9> cedk: I don't think having mutable variables and while() in Relatorio makes it crappy. I think it just completes it | ||
| 2011-12-05 14:25 <cedk> zxq9: no template are not for programming !!! | ||
| 2011-12-05 14:25 <cedk> zxq9: no template are not for programming !!! | ||
| 2011-12-05 14:26 <zxq9> cedk: Then what is <if test=""> in there fore? | ||
| 2011-12-05 14:26 <zxq9> cedk: We should remove it? | ||
| 2011-12-05 14:26 <cedk> zxq9: this is not assignation !!! | ||
| 2011-12-05 14:26 <zxq9> cedk: What is <with vars=""> for? | ||
| 2011-12-05 14:26 <cedk> zxq9: comes from Genshi and it should not be used | ||
| 2011-12-05 14:27 <zxq9> cedk: I think it would be more straightforward to be more strict then... like maybe ONLY allow calls to methods and objects inside models. | ||
| 2011-12-05 14:27 <zxq9> cedk: Then there would be no choice, and everything would still be codable, just only inside the Python code. | ||
| 2011-12-05 14:28 <zxq9> cedk: I don't think this is a bad way, really, so long as a few more tutorials are available/updated. | ||
| 2011-12-05 14:28 <cedk> zxq9: I did not decide to include with but for sure it was a mistake | ||
| 2011-12-05 14:30 <zxq9> cedk: So your vision is Relatorio dropping <with vars="">, and gaining the ability to work directly with bitstream.seek() for images? | ||
| 2011-12-05 14:30 <zxq9> cedk: I dont think that is a bad thing, it just needs to be documented well. | ||
| 2011-12-05 14:31 <zxq9> cedk: And maybe that means really splitting the Relatorio documentation away from constant Genshi references. | ||
| 2011-12-05 14:31 <cedk> zxq9: patch is welcome | ||
| 2011-12-05 14:32 <zxq9> cedk: How about documentation as well? How do I help with making Relatorio docs up to date? | ||
| 2011-12-05 14:33 <cedk> zxq9: write it | ||
| 2011-12-05 14:33 <zxq9> cedk: Who do I submit to? | ||
| 2011-12-05 14:33 <cedk> zxq9: bugtracker | ||
| 2011-12-05 14:33 <zxq9> cedk: OK. | ||
| 2011-12-05 14:34 <zxq9> cedk: Next question, technical one this time -- how do I know which ids to pass to a fields.Function()? Is it usually a pyson thing? | ||
| 2011-12-05 14:34 <pjstevns> v | ||
| 2011-12-05 14:37 <cedk> zxq9: I don't understand | ||
| 2011-12-05 14:42 <zxq9> Like in a getter(ids, name), where does ids get passed from? | ||
| 2011-12-05 14:44 <cedk> zxq9: it comes from the records you are reading | ||
| 2011-12-05 14:49 <zxq9> Ah... ok. This makes more sense now. It was sort of magic to me before -- which is a little scary. | ||
| 2011-12-05 15:52 <zxq9> cedk: Hmmm... I'm trying to take the image data from the binary field and save it as /tmp/image.jpeg, define a file object and return it and the mime type in a function. | ||
| 2011-12-05 15:52 <zxq9> cedk: Am I going in the correct direction or is this wrong to pass an image to a report? | ||
| 2011-12-05 16:01 <cedk> zxq9: yes it looks like | ||
| 2011-12-05 16:07 <zxq9> I'm having a 'char buffer type not available' problem, but I think there is a way to avoid this. | ||
| 2011-12-05 16:08 <zxq9> I think the way I'm calling the method is actually pulling the data as a string from the server, then passing the whole thing as an argument to the method. | ||
| 2011-12-05 16:08 <zxq9> I want to just call the method and have it copy the correct image from the current id into a file. | ||
| 2011-12-05 16:10 <zxq9> And this is where I'm lost on the id thing. | ||
| 2011-12-05 16:16 <zxq9> cedk: http://fpaste.org/GmaE/ and http://fpaste.org/4h8P/ is what is there now, but this is pulling the file data from server to client and pushing it back to write to a file to send again, I think (ridiculous). | ||
| 2011-12-05 16:17 <zxq9> cedk: The binary field face_pic should just get copied once on the server side, but I don't know how to access just the current record from within a method like this. | ||
| 2011-12-05 16:19 <zxq9> cedk: and of course the <image:> part is not written like that, it is the name string of a field | ||
| 2011-12-05 16:19 <cedk> zxq9: why not using StringIO? | ||
| 2011-12-05 16:20 <zxq9> You mean like str(binaryfield)? | ||
| 2011-12-05 16:20 <zxq9> Or maybe I don't know about StringIO? | ||
| 2011-12-05 16:21 <grasbauer> zxq9: StringIO.StringIO(string_from_the_binary_field) | ||
| 2011-12-05 16:21 <zxq9> Ah, it is a Python library class? I neefd to rad about it. | ||
| 2011-12-05 16:23 <zxq9> How would this look? http://fpaste.org/P9JE/ ? | ||
| 2011-12-05 16:25 <zxq9> So StringIO is like virtual files or files in core memory? | ||
| 2011-12-05 16:25 <zxq9> That's way faster than making a /tmp file | ||
| 2011-12-05 16:31 <zxq9> Hmm... pic = (StringIO.StringIO(image), 'image/jpeg'); return pic; makes open office think the document is corrupted, which is interesting. | ||
| 2011-12-05 16:31 <cedk> zxq9: have you the last version of relatorio? | ||
| 2011-12-05 16:32 <zxq9> erm... good question. Lemme check. | ||
| 2011-12-05 16:33 <zxq9> cedk: http://fpaste.org/jQbg/ Should this work or am I still doing something silly? | ||
| 2011-12-05 16:33 <cedk> zxq9: it should | ||
| 2011-12-05 16:34 <cedk> zxq9: but we got sometimes buffer exception because StringIO can not work on buffer from psycopg | ||
| 2011-12-05 16:34 <cedk> zxq9: so adding a str conversion is good | ||
| 2011-12-05 16:35 <zxq9> cedk: Like http://fpaste.org/O2PA/? | ||
| 2011-12-05 16:36 <zxq9> No, I get the old str object has no seek method thing again that way. Must not be what you meant. | ||
| 2011-12-05 16:36 <cedk> zxq9: no the other way | ||
| 2011-12-05 16:37 <cedk> StringIO(str(image)) | ||
| 2011-12-05 16:37 <zxq9> oh... haha. I see. | ||
| 2011-12-05 16:39 <zxq9> cedk: Calling from "image: person.person.get_pic(person.person.face_pic)" now gives a much more promising error: "'module' object is not callable' | ||
| 2011-12-05 16:41 <cedk> zxq9: you can not call method on BrowseRecord | ||
| 2011-12-05 16:44 <cedk> zxq9: the simple way is to put the method in the localcontext of the report parser | ||
| 2011-12-05 16:45 <zxq9> cedk: Is there an example of this I can read? I'm unclear on exactly where the "report parser" is. | ||
| 2011-12-05 16:47 <cedk> zxq9: http://hg.tryton.org/modules/account/file/e0e172026e46/account.py#l1167 | ||
| 2011-12-05 17:14 <zxq9> cedk: Weird. With an update to Relatorio this actually works without the method: <image: (StringIO(str(person.person.face_pic)), 'image/jpeg') | ||
| 2011-12-05 17:15 <zxq9> cedk: And thank you for the example. This will be useful for re-writing my crazy document system! | ||
| 2011-12-05 18:20 <udono> cedk: hi, what is the schedule for 2.2.1? | ||
| 2011-12-05 18:21 <cedk> udono: don't know | ||
| 2011-12-05 18:26 <udono> cedk: ok. | ||
