问题
For example :
i need an Animals table which will contain animal_type as Object or T type as foreign relation field.
then i will have 10 different tables like Dog/Cat/Horse etc.
at the time of insertion based on type of animal i would set animal_type of Animal object.
I don't want to take multiple databaseField for each type as a foreign relation, instead i need one generic field , Using ormlite version 5.0.
please refer this json:{
"animal": {
"type": 1,
"content": {
"items": [
{
"title": "Image",
"desc": "This is item with image",
"media": {
"url": "https://upload.wikimedia.org/wikipedia/commons/9/99/Earth_rise_from_the_Moon_AS11-44-6550_2.JPG",
"type": 0
},
"options": [
{
"title": "View",
"value": "view"
},
{
"title": "Download",
"value": "download"
}
],
"url": "https://commons.wikimedia.org/wiki/File%3AEarth_rise_from_the_Moon_AS11-44-6550_2.JPG"
}
]
}
}
}
