@teolemon Rough around the edges, but it does work!

In the web app:

https://prices.openfoodfacts.org/app/products/3560071052133

Btw I was not logged in. Are we supposed to be logged in for prices?

[teolemon]

• proof is compulsory
• login is compulsory

We're in risk otherwise @raphael0202 @raphodn

[teolemon]

@monsieurtanuki you need a currency dropdown

[monsieurtanuki]

• proof is compulsory
  => already is
• login is compulsory
  => ok
• currency dropdown
  => it was in my todo list, as well as the proof type (price tag or receipt)

Shouldn't we also define the source (e.g. web app or Smoothie or whatever)?

[teolemon]

the source is indeed a good idea, not sure openprices supports that @raphodn

Yes good idea ! Though it could easily be forged, no ? Do you already have a similar mecanism in OFF ?

[monsieurtanuki]

In off-dart we use the user agent:

OpenFoodAPIConfiguration.userAgent = UserAgent(
  name: '<Name of your app>',
);

[monsieurtanuki]

@raphodn To be more specific, our user agent data will be used with the following parameters for most GET requests:

• app_name (the only mandatory parameter)
• app_version
• app_uuid
• app_platform
• comment

[teolemon]

It's used in conjonction with auth @raphodn
any API user could pass bogus comments, but in practice you'll see the username

[teolemon]

It's mostly used to debug API implementation issues, and identify if newer versions of the clients still have the issue

[raphodn]

Ok I'll look at this today, to add a price.source field (and also a proof.source ?), that stores the user agent's app_name

[monsieurtanuki]

I've just added 3 prices from Smoothie.
I'm about to start the background task, which seems relevant.
