c# - NopCommerce add new table - invalid column name 'Product_Id1' -

i'm figting add together new table in mycommerce engine;

relation

[product] 1..* [awards]

code files:

public partial class awards : baseentity, ilocalizedentity { public virtual product product { get; set; } public string awarddescription { get; set; } public guid awardguid { get; set; } public int product_id { get; set; } } public partial class awardsmap : entitytypeconfiguration<awards> { public awardsmap() { this.totable("awards"); this.haskey(p => p.id); this.property(p => p.awardguid).isoptional(); this.property(p => p.awarddescription).isoptional(); this.hasrequired(p => p.product) .withmany(pt => pt.productawards) .map(m => m.totable("awards")); } } public partial interface iawardsservice { void deleteawards(awards awards); ilist<awards> getallawardss(); awards getawardsbyid(int awardsid); void insertawards(awards awards); void updateawards(awards awards); }

and awardsservice.cs class implements iawardsservice interface (in same way producttagservice.cs)

product.cs code snippet:

private icollection<awards> _awards; public virtual icollection<awards> productawards { { homecoming _awards ?? (_awards = new list<awards>()); } protected set { _awards = value; } }

but every time load product fromdatabase , seek load productawards proparte error

invalid column name 'product_id1'. invalid column name 'product_id1'.

what's going on ?

edit

i saw customer, customeraddress, address tables , i've modified mine classes looking same ones , it's working.

please check mapped table having same column name defined in class.

here looks conflict throwing error invalid column name 'product_id1' , name of property in class product_id.
