Is there a repo for the website or should I just write up suggestions somewhere

Also, by any chance are any of you going to React London next week?

Is there a repo for the website or should I just write up suggestions somewhere

I think there is https://github.com/ponyorm/pony-doc

Probably you can even just create Pull requests there

I think there is https://github.com/ponyorm/pony-doc

that's docs.ponyorm.com, not the site

Oh, sorry, I thought you meant that.

Is there a repo for the website or should I just write up suggestions somewhere

we don't have public repo for the site at this moment, the best way is to write suggestions here, I think

fair enough, I'll have another look at it after work then

Also, by any chance are any of you going to React London next week?

we don't plan London next week, but the next 5 month I will be in the US, so if we can meet there it would be great ?

Haha, I don't think there's much of a chance there

We use Django & React at work so my company's sending me to React London. Figured it would be cool to meet up with any Pony users, had there been any

great do you think your company would be interested in the Diagram Editor, once it supports Django?

Possibly, although I think the reaction I'd get to that suggestion is "we could just write the models.."

that's fine

I'll definitely bring it up once you do though

thanks! any form of feedback if greately appreciated

Sorry, but pony 0.7.1 requires Python of one of the following versions: 2.7, 3.3-3.6. You have version 3.7.0a0 https://travis-ci.org/luckydonald/pbft/jobs/214432324

I'll fix it tomorrow in dev version on GitHub

I have not started ponyorm yet but syntax looks like my beloved LINQ in MS EntityFramework

So I am dumping my learning SQLALCHEMY for this sure

I hope Pony gets more exposure

Popular = more tutorials and great learning resources

Popular = more tutorials and great learning resources

Please explain???

I mean if Pony ORM is known to poeple as much as SQLAlchemy we can have books, videos and courses to make learning easier for new comers

Okay

Great

Glad to hear

Hello! I use postgres schemas. _table_ = (schema, 'molecule') and then I run generate_mapping(create_tables=True) on existing db i receive: DBSchemaError: Table "db_data"."molecule" cannot be created, because table "molecule" (with a different letter case) already exists in the database. Try to delete "molecule" table first. but on sqlite db this works fine

I remember this works also on postgres without schemas

What would be the best way to ask a Database object for all of its models?

Oh, I didn't know there was an entities attribute.

Is there a parent class for generic ORM errors?

PonyORM errors*

Is there a parent class for generic ORM errors?

Yep: class OrmError(Exception): pass

Thanks!

Where can I import that from

gmail.com

from pony.orm.core import OrmError

Perfect, thanks

gmail.com

Best answer :D I like your humor

jajajajajajaja

Hi everyone]

I just found this ORM

and want to learn more

I know few about python code, and not with database such as SQL,oracle, etc

so basically I know only python code

Hello

Hi. So, what's your question?

I am wondering if there is a migration tools for pony yet

The migration tool is unreleased yet. At this moment we are trying to using it and discover some bugs. We want to fix the most critical bugs before the migration tool is released, because bugs in migration tool can lead to database corruption. I hope we will release it soon.

Okay..

Is it convenient to use this ORM within django?

Many components in Django (for example, admin UI) assume that you use Django-ORM and will not work otherwise

Ouu...

I have slow internet connection

So I haven't try the online editor that Pony ORM had

Does it works like sqlyog or something?

Is there any offline one?

I have no experience with SQLyog, but from the first look it presents schema in terms of tables, while Pony editor present it in terms of entities. It's online-only

Is there any offline one?

You can work with the editor offline. You need the connection only when you open the diagram and when you save it.

Yeah we are waiting for a selfhostable version too

Would be great

Pony is rewritting how it names rows in tables for the next version correct?

Yes

Will the rewrite allow for class A(db.Entity): name = Required(str) class B(A): name = Required(str) other = Optional(int)

Oops I wrote the example wrong

Okay fixed it

No, in the next release we will just changes names of many-to-many tables and the corresponding indexes/foreign keys Why you want to define schema like in your example?

I want to have a generic Entity subclass with helper methods, where unrelated tables might have similar fields

If B inherits an attribute from A, it doesn't need to redefine it. If it is actually an attribute with a different meaning, maybe you can give it slightly different name

Okay thanks, I'll do that

Be aware, that currently if one entity inherits from another, they share the same table

Yeah I think that the helper entity just won't have any columns of its own

Actually I think I could get away with a Mixin

which doesn't actually inherit from Entity

If one entity inherits another and the table is shared, can the child's columns even be non-nullable?

no, it may be required, in a sense that Pony will check in Python, that the object instances with that column have a non-empty value in it. But in the table the column will be declared as nullable

What would be the best way to write code that takes an entity and produces an WTForm

Currently we don't have a ready solution, but if you want some generic code, you can analyze obj._attrs_ or entity_class._attrs_ in order to see attribute definitions

My current plan was the use _attrs_, thanks

Where can I find all of the possible data types for columns, so I can map them to form types?

Each data type has corresponding database converter class in dbapiprovider.py (the converter classes are inherited and redefined in specific providers such as dbproviders/sqlite.py)

Is there anything like sandman2 for PonyORM?

I'm no aware of that

I think no

90% of the time you don't want a directly generated REST API

that being said, something like DRF for pony would be neat

I agree, this is mostly just an experiment

How can you access the length attribute of a string entity?
