You have to provide rights for this object

like this example

<record id="id" model="ir.model.access">

<field name="name">name of objr</field>

<field name="model_id" ref="module_model_name"/>

<field name="perm_read" eval="1"/>

<field name="perm_create" eval="1"/>

<field name="perm_write" eval="1"/>

<field name="perm_unlink" eval="1"/>

</record>

Yeah, you just simply need to provide the security rules for your model. Any above answers should work fine. 

P.S. Just trying to earn some karma, so I can ask my own question. Please, upvote 1 time <3 

Dear Aboorva,

It's Simply Access Control List  Error, For logged in user group there's no Access to read "market.process" model, 

Temporary Solution is login as admin and open application with developer mode Goto : Settings -> Security -> Access Control List -> Create , choose model as "market.process" and choose user group, provide ACL for read. then login as same usergroup you have choosen. 

Permanent Solution is Open ir.access.csv from your module security folder provide ACL as per shown below,

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink

access_to_market_process,access.to.market.process,module_name.model_market_proces,user_group,1,1,1,01

If you already gave ACL for that User Group then Check Record Rules for "market.process" model.

Thank you.
