[SOLVED] A Farmer Unit That Plants Resources

Inspired by AOM's Botanist Mod I wanted to create a Farmer Unit that can Plant Resources (Without gathering them). So Far, I got that to work! Now I want to specify the Mechanic of planting the resources, like some Resources can only be planted by a specific Civilization (TraitType) and having a PrereqTech/PrereqCivic. I have tryed to do that via the New Table that lets you plant the Resources, but I get no results. I can still plant a Resource by any Civilization despite I have specifyed it to only be planted by a specific Civilization (with TraitType) and the PrereqTech/Civic doesn't work neather.

Here is the Complete SQL Code:

Code:

create table Farmer_Resources(
    ResourceType varchar(100),
    UnitType varchar(100) null,
    ImprovementType varchar(100) null,
    PrereqTech        varchar(100) null,
    PrereqCivic       varchar(100) null,
    TraitType       varchar(100) null,
    FOREIGN KEY (PrereqTech) REFERENCES Technologies (TechnologyType) ON DELETE SET DEFAULT ON UPDATE SET DEFAULT,
    FOREIGN KEY (PrereqCivic) REFERENCES Civics (CivicType) ON DELETE SET DEFAULT ON UPDATE SET DEFAULT,
    FOREIGN KEY (TraitType) REFERENCES Traits (TraitType) ON DELETE SET DEFAULT ON UPDATE SET DEFAULT
);

insert into Farmer_Resources(ResourceType)
select ResourceType
from Resources
where ResourceType in
(
    --Base Game
    'RESOURCE_BANANAS',
    'RESOURCE_RICE',
    'RESOURCE_WHEAT',
    'RESOURCE_CITRUS',
    'RESOURCE_COCOA',
    'RESOURCE_COFFEE',
    'RESOURCE_COTTON',
    'RESOURCE_DYES',
    'RESOURCE_INCENSE',
    'RESOURCE_SPICES',
    'RESOURCE_SUGAR',
    'RESOURCE_TEA',
    'RESOURCE_TOBACCO',
    'RESOURCE_WINE',
    'RESOURCE_SILK',
    -- Rise and Fall
    'RESOURCE_OLIVES'
);

update Farmer_Resources
set ImprovementType =  'IMPROVEMENT_PLANT_'|| replace(ResourceType, 'RESOURCE_','');


update Farmer_Resources
set UnitType = 'UNIT_FARMER',
ImprovementType =  'IMPROVEMENT_PLANT_'|| replace(ResourceType, 'RESOURCE_','');

insert into Types(Type,Kind)
select
ImprovementType as Type,
'KIND_IMPROVEMENT' as Kind
from
Farmer_Resources;

insert into Improvements(ImprovementType,Name,Description,Icon,Buildable,CanBuildOutsideTerritory,PlunderType)
select
ImprovementType,
'LOC_'|| ImprovementType ||'_NAME' as Name,
'LOC_'|| ImprovementType ||'_DESCRIPTION' as Description,
'ICON_IMPROVEMENT_PLANTATION' as Icon,
1 as Buildable,
1 as CanBuildOutsideTerritory,
'PLUNDER_NONE' as PlunderType
from Farmer_Resources;

insert into Improvement_ValidBuildUnits(ImprovementType,UnitType)
select
ImprovementType,
UnitType
from Farmer_Resources;

insert into Improvement_ValidTerrains(ImprovementType, TerrainType)
select
    distinct
    br.ImprovementType,
    vt.TerrainType
from Farmer_Resources br
join  Resource_ValidTerrains vt on br.ResourceType = vt.ResourceType;

insert into Improvement_ValidFeatures(ImprovementType, FeatureType)
select
    distinct
    br.ImprovementType,
    vt.FeatureType
from Farmer_Resources br
join  Resource_ValidFeatures vt on br.ResourceType = vt.ResourceType;

update Farmer_Resources
set PrereqTech =  'TECH_MACHINERY' where ImprovementType =  'IMPROVEMENT_PLANT_BANANAS';

update Farmer_Resources
set PrereqTech =  'TECH_MACHINERY' where ImprovementType =  'IMPROVEMENT_PLANT_SILK';

update Farmer_Resources
set TraitType =  'TRAIT_CIVILIZATION_PLANT_RESOURCE_BANANAS' where ResourceType = 'RESOURCE_BANANAS';

update Farmer_Resources
set TraitType =  'TRAIT_CIVILIZATION_PLANT_RESOURCE_SILK' where ResourceType = 'RESOURCE_SILK';

INSERT INTO Types
        (Type,                                Kind)
VALUES    ('TRAIT_CIVILIZATION_PLANT_RESOURCE_BANANAS',                'KIND_TRAIT'),
        ('TRAIT_CIVILIZATION_PLANT_RESOURCE_SILK',                'KIND_TRAIT');

INSERT INTO Traits
        (TraitType,                                Name,                                Description)
VALUES    ('TRAIT_CIVILIZATION_PLANT_RESOURCE_BANANAS',                'LOC_TRAIT_CIVILIZATION_PLANT_RESOURCE_BANANAS_NAME',                'LOC_TRAIT_CIVILIZATION_PLANT_RESOURCE_BANANAS_DESCRIPTION'),
        ('TRAIT_CIVILIZATION_PLANT_RESOURCE_SILK',                'LOC_TRAIT_CIVILIZATION_PLANT_RESOURCE_SILK_NAME',                'LOC_TRAIT_CIVILIZATION_PLANT_RESOURCE_SILK_DESCRIPTION');

INSERT INTO CivilizationTraits
        (CivilizationType,                                TraitType)
VALUES    ('CIVILIZATION_KONGO',                'TRAIT_CIVILIZATION_PLANT_RESOURCE_BANANAS'),
        ('CIVILIZATION_KONGO',                'TRAIT_CIVILIZATION_PLANT_RESOURCE_SILK');

I have also tryed the TraitType and The Prerqs Without the Foreign Key but no results.

Here is The Lua Code (I don't think that it has any effect on this problem, but if it can be of any help, here it is!):

Code:

include("PopupDialog");
local NONE = -1;


function OnImprovementAddedToMap(locationX, locationY, improvementType, eImprovementOwner, resource, isPillaged, isWorked)
    local plot = Map.GetPlot(locationX,locationY);
    local improvement = GameInfo.Improvements[improvementType];
    if improvement ~=nil then
        PlantSeeds(improvement,plot);                  
    else
        print('improvement type '..improvementType..' not found');
    end
end

function PlantSeeds(improvement,plot)
    local found_transplant_type = false;
    local transplant_types = {};
    table.insert(transplant_types,'RESOURCE');
    for i in string.gmatch(improvement.ImprovementType, "[^_]+") do
        if i == 'PLANT' then
            found_transplant_type = true;
        elseif found_transplant_type then
            table.insert(transplant_types,i);
        end
    end
    if found_transplant_type then
        local transplant_resource_type = table.concat(transplant_types,'_');
        ResourceBuilder.SetResourceType(plot, GameInfo.Resources[transplant_resource_type].Index, 1);  
        ImprovementBuilder.SetImprovementType(plot, NONE, NONE);
    end
end
Events.ImprovementAddedToMap.Add(OnImprovementAddedToMap);
print('FARMER loaded');

Can anyone help me getting this to work? Thanks in Advance !!
