Create two resources with the same name fails

[Antoine Eiche]

Two networks with the same name in the same tenant can not be created while this is allowed by neutron. This is also true for routers and maybe for some other kinds of resources.

It fails because fq_name of these two resources are identical.

For instance, we create a first network 'net-default'
$ neutron net-create net-default
If we create a second network with the same name
$ neutron net-create net-default
the following exception is raised:
RefsExistError: ['default-domain', 'demo', 'net-default'] already exists with uuid: 9236330e-8f05-49c7-9a5b-f4343e9638af

Which neutron plugin are you using? I just tried it on the latest build and it is working as expected:

root@b4s9:/usr/lib/python2.7/dist-packages/schema_transformer# neutron net-create n1

Hello Sachin,

I'm using the commit ID 9da9fae96090a299974be5609978c5b05085d6c5 (in
repository https://github.com/juniper/contrail-neutron-plugin).

Strange that you don't reproduce this problem. Edouard Thuleau has also
reproduced it today.

Antoine.

I'm using the plugin v3.
Edouard has tried with the plugin v2 and he was not able to reproduce it.

So, it is working for plugin v2 but not for plugin v3.

Create several resources with the same name

When a resource is created, if its name already exists, the uuid of
the resource is appended to its name and fq-name. The display-name is
used to store the name provided by the user.
