Re: [web2py] Re: Create a service running continuously
Hi thanks for the suggestions. Sorry for not responding sooner. I figured a
way of working and been working abroad for a few days...) so I haven't
tried your suggestions.
What worked for me was I wrote a service that returned the contents of a
table that define the bot commands and called it using requests in Python.
The response contains the data as json. Then I connect to my Slack room and
listen for commands that invoke my bot. the bot responds according to the
commands received and looked-up responses read from the DB.
I suspect using the DAL directly could have achieved the same goal and also
retain the DB connection to store stuff too if required - but right now I
don't need to do that.
Happy to share my code if you have a similar need to drive a Slack bot.

[web2py] Calendar popup displays away from date fields in Internet Explorer
Hi, I'm using the calendar popup on Firefox and Chrome and all is well. But on Internet Explorer, the popup appears several inches higher on the page away from date fields. If your date field is a couple of inches from the top of the displayed window, the popup appears off screen. Most disconcerting. I'm using Web2py 1.99.2, but I took the calendar.js and calendar.css from the latest version of Web2py (1.99.7) and it exhibits the same behaviour in my environment. Does anyone have any suggestions for what I'm doing wrong? Is there some browser-specific code I should be using somewhere? thanks, Paul. --
[web2py] Re: column auth_user.registration_id does not exist ERROR AFTER UPGRADE to 1.99
I just had the same problem on a test version of my apps. I'm using MYSQL. The field is missing and it isn't being autocreated because Migrations=False in my db.py model, I have auth.define_tables(migrate=False) Using fake_migrate True and then trying to migrate to reset doesn't work either. I get Dupe table message then. What is the definition of this field? It seems to be created by code in tools.py - but what's the MySQL field definition - I'll create manually. I expect to have the same problem in another 20 or so MySQL DBs. My guess is it's a MySQL specific issue. I have update DB defs manually (using scripts) for two years as it's too much hassle to do it any other way in a large complex DB. Paul G.
[web2py] Re: dropbox python api
Hi, I got distracted by other things and only just came back to this. The problem I was having was in my code was the token was 'disabled or invalid'. I'm sure this is resolved by using the callback in the redirect back from the Dropbox site. I commented out the code that's not relevant for me in your code and it works fine now. As for using cron - I expect you could skip the redirect and go from line 191 directly to 204. Presumably you need a try/except around 204? Paul.

[web2py] Re: dropbox python api
I just started looking at Dropbox yesterday. I've created some code that works in the python interpreter just fine, but when I paste to a web2py controller it fails. I suspect it's because the Dropbox module uses a variable calls 'session' that actually uses the Web2py session variable. Is there an easy way around this (e.g. do I need to put the Dropbox code into a model?) or do I need to use your code mentioned above? Did you get feedback on the code - is it reliable?

[web2py] Re: IMPORTANT
My 2p worth. I run a couple of communities relating to software testing. One is public (uktmf.com) one is private (testers-retreat.org) and this kind of discussion arises from time to time, often about face to face communications. People who are passionate DO get upset - it happens. Testers are a particularly pedantic lot and see their mission in life to be critical. So testers are 'ten times worse'. This forum is about web2py for users of it and developers of it. There's a famous poem by W.B. Yeats http://elise.com/quotes/quotes/yeats.htm ... tread softly because you tread on my dreams. If you share your dreams here - people will tread on them if they don't share them. Period. So if you have a passion that isn't web2py or python or related - watch out - you may offend and be offended. For example. This is just an EXAMPLE. No offence Gour, but I don't think your quote stacks up. Let me critique it very quickly. All concepts are mental contrivances. So conceptions of anything are mental speculations. In ANY world. So the quote says nothing and its just plain wrong anyway. Have we enriched humanity by sharing the quote or critiquing it? Of course not. It's just noise. Now everyone could critique everyone elses quasi-religious, -mystic or -philosophic statements made in the forum. But it really won't get us anywhere. It's just noise and detracts from the purpose of the group. So put your non-web2py musings somewhere else. It's not because you may offend it's because criticism may offend you and there are plenty other forums for that kind of thing. So the policy should be - bring germane content in here or expect to be criticised - politely at all times of course.

[web2py] web2py_ajax.js - jQuery().html v DOM innerHTML issue
Hi, Today, I upgraded my web2py version from 191.6 to 1.97.1 - all went well except where I had used the autocomplete jquery plugin on jquery dialog boxes. (I do thsi lots of times). Let me explain. 1. I create a dialog box using jquere dialog plug in 2. Then I use Web2py ajax to populate the div with the content which is a form 3. After the ajax load, I use a javascript routine with a timer to attempt to assign the autocomplete addin to a select field in the form. All worked well in the upgrade except this. The autocomplete code fails with a message saying the select has no method 'combobox' Now, I tracked the 'problem' down to the line of code in web2py_ajax.js in the jQuery ajax call that puts the ajax content into the div in my dialog boxes: v 1.97.1 jQuery(# + t).html(msg); (the new way - DOES NOT WORK) v 1.91.6 document.getElementById(t).innerHTML=msg; (the old way - WORKS) So I've made that change temporarily in web2py_ajax.js. Looking around the web, there seems to be a general view that innerHTML isn't the best way to load content into fields. Can anyone explain the difference in behaviour and what I need to consider in adopting the new style ajax routine? Or is this a bug???

[web2py] Using my own dropdown lists
Hi, I have a screen transaction that uses a select drop down list that i create myself using code in my controller. All works well except when I have an error on another field, Web2py highlights the error on screen, but if I've made a selection using the drop down list, the selection made (if different from the original stored value) is not kept and the dropdown returns to the original value. If I have errors in a form, how do i pass the value selected on a page to the routine in my controller that generates the drop down? I thought it was form.vars.fieldname - but it doesn't seem to work :O( How do I capture the 'last submitted' values on a form so I can re- display them on a form or use them in my controller? Any suggestions? Paul.

[web2py] Looking to make contact with (UK based) dev/collaborators
Hi, I'm currently building an application which we will host on our servers as a pay-for-use commercial service. We're making contact with some beta evaluators who we hope will help us to refine the product and hopefully, pay for the service and be our initial reference sites. The website will be testela.com - its not live yet - but our staging/ test and live sites are set up under different urls. Currently, I'm doing all the coding, but I need to come out of my cave and 'get out there' to sell the concept and the product. So I'm looking to offload some, perhaps all of my dev workload. I have a tester (who is my non-exec chair :O)), and I'll do some testing and act as Product Owner. We'll probably operate a variation of Scrum to manage the work. The tool is intended to support large projects to help them manage requirements, collect user stories to example the requirements and to build comprehensive system/acceptance tests. A smaller and different cut of the functionality will be offered as a support tool for Agile projects using Scrum. The tool will evolve to include full test execution management and probably integration with test execution tools. We'll use the tool to help us manage the project to build the tool. (Eating own dogfood etc.) I'm interested in hearing from smart developers with experience in any (or even all!) of the following. I've separated the current from the futures. What we use today: Web2py, Python, HTML, CSS (obviously!) (Ubuntu) Linux, Apache MySQL jquery, jqgrid, AJAX Futures: Web Services for clients to extract data from the tool (where required) Testing frameworks (to link to tools that developers/system testers use) Source code management tool (possibly Git) and maybe a reliable automated build process - this is a priority Interfaces to test execution tools such as Selenium, Webdriver or proprietary tools like QTP etc. etc. And oh, yes, we expect to pay for services rendered! The relationship could evolve into a full time role or long term partnership. Let's see. :O) I'm based in Maidenhead, UK. Now it would be nice to meet people face to face in the UK, but that's a nice to have and if you are on the other side of the world - maybe it's not a problem. Drop me a note here, or mail me at paul at gerrardconsulting dot com. (Our drupal based website is also due for a refresh so it doesn't mention Testela - yet). Thanks.
[web2py] DB Select with date criteria
Hi, I can't find a usable reference to selecting records from a database table based on the value of datetime fields. Here's my situation: I have a table with two date fields: db.define_table(announcements, SQLField(validfrom, datetime, notnull=True, default=datetime.today(), label=Valid from), SQLField(expires, datetime, notnull=True, default=datetime.today()+timedelta(days=3), label=Expires), SQLField(author_id, db.auth_user, default=session.user_id), SQLField(subject, string, length=100, notnull=True, label=Subject), SQLField(message, text, notnull=True, label=Message)) I want to select records that are valid as follows: anns = db( ( db.announcements.validfromdatetime.today() ) and \ ( db.announcements.expiresdatetime.today() ) ) .select() That is, expires date is in the future and the validfrom date is in the past. This code doesn't seem to work, as all records are returned, regardless of the date values. This must be a common requirement - any suggestions?
[web2py] Re: DB Select with date criteria
Hi,
Many thanks. Tried it and it didn't work. I had a rather subtle error
in my code it seems... and then it worked just fine.
Sometimes just changing some code rather than staring at it triggers a
chain of failure and thinking events and the solution emerges!
Thanks for the tip - much appreciated.

[web2py] Re: Should we have a feature freeze and stability maintenance period in future?
. Although I haven't spent too much time with Mercurial, most concepts don't change, and implementation well... that's all it is really. I had look @ your src repository and I find it is very telling of how you do things and what is important. As I understand, the goal is to meet 2 separate requirements that inevitably impact one another with current structure. The desired outcome: no freeze of the code line while allowing for planned testing iterations to move forward (while enabling Mr Di Pierro to maintain those elements of the current model which are important to him). I think it's entirely doable and please don't hesitate to stop me if I get carried away... I would like to start, if there are no objections, by getting a high level understanding of current practices. So, I'll throw a few questions out there. (I will try t keep the number of questions short – although it may not appear that way). Perhaps, this could be taken to another area to minimize the ruckus? I like the idea of getting a group together and collaborate on developing a proposal. As the more input we have, the better we can serve this type of development model (the concept of contributors) in the web2py dev world in particular. I see that Mr Di Pierro commits all changes to the single branch (default). Here's are a few questions with that: Where do developers check-in or commit their changes while in development? Where does the src going to dev come from and at what frequency does it get synced with the reference code line (if at all) ? Is the reference code line stable (no changes) or is it in constant flux? Since Massimo, is doing the commits, I assume that everybody keeps a sandbox copy of the src? Is there a mechanism in place which makes sure that everyone is working off the same starting point? If not, how are merge conflicts handled presently? Does the code get reviewed before making its way to Massimo who will be committing the changes (or not committing)? As the “release guy”, my first and most important consumer of builds is QA - the testers usually get first dibs on my time ;) - as they are the ones blessing builds and enabling them to move to the next levels. I tend to want to have them in mind when writing automation and making sure they can interface as smoothly as possible to my automation with there own. When going to Test, what get's handed off (src or build)? Is there any regular automated/manual testing? Or is it the case where bigger testing efforts are done later in the release cycle? how are builds identified with those test results? Good release strategies do help, so here are just a few questions on that subject: Have you a defined plan for release strategies? (i.e. moving forward between releases from 1.83.x to1.84.x, to 1.90.x etc.) - or are releases treated as milestones? milestone strategies within those releases? how do you keep track of previous releases? So, depending on the extent of adherence to release practices we want to look at, there are many elements worthy of attention. I am ready and willing to spend time in helping web2py plan and implement release methodology (if that is desired) in line with your growth expectation (which I can only imagine it being very high). What I can do to start is setup a structure on Google (although i have noe clue yet what the procedures are yet to get that going... a simple sign up?) and play with a few ideas. So, where do we go from here, meaning how do we get a group of interested people to join in? I am open for discussion with anyone interested.

I'll probably use The Grinder (http://grinder.sourceforge.net/) to stage these tests, but that won't be for 5-7 weeks I think. I'd be very interested in collaborating to create some form of test automation regime for the Web2py infrastructure and applications using either available tools or maybe writing our own framework. (I'm looking to build an interface from my tool to things like Fit/Fitnesse (or replace them) and Selenium as I focus very much on acceptance testing).

If you'll allow me, I'm just curious as to the narure of your current branching strategy wrt the subject of the thread? In my experience, freezing a code line is rarely beneficial, least of all to the release going forward. So, was wondering if finding the correct branching strategy (as well as defining an appropriately well matching high level root folder structure in your source CSM) would help in sorting out such things as separating out and accommodating the need for stability, moving forward and any iterative requirements in your release cycles? (I heard someone last year year - obviously someone of the newer generation - call this the need for speed ;) ) But regardless, if at all interested I'd be happy to do my part and help out in any way I can if such plans are being considered. BTW - I was hired to revamp and restructure release management processes last spring for US based company, and web2py (with some Flex pieces in it for demo purposes) was what I used to to showcase and spread the word about the proposed changes :) On another note: I saw that some PDF libs were on there way for web2py Awesome! I am looking forward to that! :) I made a web2py app a few weeks ago (mixing the ReportLab's tool kit and Flex/iFrames) so that the kids in my daughter's violin class (yeah ok, this may be a little weird, but...) could generate fingerboard position markers (which are then convert to printable PDF templates) so that the kids could create the exact position markers for their instrument (I think she hates things that are pitchy). Anyways, did not want to use LiveCycle data services (with flex) for this (although it does do some good things), and even though the results I got with what I used were a little ok (or most probably, the problematic parts had something to do with the guy writing the code :) ), generating PDF with good tooling will be great!

[web2py] Ajax works differently in IE and Firefox
Hi, I have a view that displays rows of data, each of which a form that can be edited (passed in an array). Each row has (among other fields), two SELECT lists. The values displayed in the second list depend on the first. I use Ajax to refresh the second list if the first one changes. Using IE 8 on Windows - it works absolutely fine. The right elements are listed in the second list and the update saves the correct references for both list. Using Firefox, the ajax function workd fine. Changing the first list makes the second list refresh correctly. However, when I select a value in the second list, and save - the record is saved but the second value is always stored as zero. (Changing a value in the second list without changing the fuirst works fine of course!) I'm stumped. Can't find anything on the list or the wider itnernet on this topic. Have I missed something obvious here? Is there a way of forcing Firefox to behave the same way as IE? Is IE working because it is buggy and Firefox behaves correctly? ??
[web2py] Problems changing table definition
Hi, I'm having great problems changing the definition of a table. I'm using MYSQL as a back end. After many problems, I ended up deleting a table entirely and trying to recreate it in my DB model. I dropped the table from MYSQL directly and tried to use the new model. Unfortunately, I get a message: table doesn't exist when I try and use it. It looks like Web2py remembers the table and tried to update what it remembers. Can this 'remembered DB' be cleared out so I can start again? I only want to change on table (and not lose all my tables :-)) Thanks, Paul.
[web2py] Re: Problems changing table definition
An updqate. I read the manual 6.4 on Migrations. I've added a migrate='tablename' aramter to the table definition call. It seems to work. So I guess I've disconnected the table definition from the Web2py table history. So far so good. So I have a more general point. Is it 'better' to manage database designs using the Web2py model or better to manage the database using the DB utilities and keep the model in sync? I understand the web2py model route ought to be better, but this is the second time I've lots hours messing around with out of sync database and models.
[web2py] Re: Problems changing table definition
Thanks - I already do nightly backups of data and code (been stung too many times before). I want to use Web2p as you say, but I've had problems in the past. 2-3 times, no matter what I've tried, I couldn't edit the DB.py file and avoid crashes. Ended up deleting tables, massaging data with MS Access, recreataing with difference nemae and reocdign etc. etc. Also, I can't point the app at an empty MySQL database and let it build the tables. Have to rely on a backup to recreate empty tables first. I haven't kept any evidence, but I will post it here next time (if it happens again). Have you had problems with MySQL users before??? Really enjoying using Web2py - I'm building a test support/management tool to support our business services. Very happy with the development progress and just a few niggles - this is one of them.
