Village don't changing popularity after defeat a raid

Hi,

 After defeating a raid you get the potion effect "Hero of the village" for two in-game days unless you die.

Your popularity wouldn't be effected by defeating the raid but the "Hero of the village" potion effect is what gives you the heavily discounted prices. Make sure to check if you have the potion effect, if not then you wont get the heavily discounted prices until you beat another raid. If you do please respond as you would have encountered a bug with the potion effect.

Hope this helped

When I provoked iron golems,iron golems still attack,even it I got hero of the village effect.

When you attack a iron golem it doesn’t matter if you have the hero of the village effect they will still attack. If you attack a villager iron golems will attack you and your popularity will go down.
