我的模型中有很多json字段。我想以字符串格式打印它们。
我使用的代码是：
data=[]
detail=details.objects.filter(Id=item['Id'])
for i in compliance:
data.append(str("Name")+str(":")+str(i.Name)+str(" , ")+str("Details")+str(":")+str(i.Details)
print data
我得到的输出是：
Name:ABC, Details:{u'Status': u'True', u'Remarks': u'No Remark'}
预期输出为：
Name:ABC, Details:Status:True,Remarks:No Remark
任何帮助将不胜感激。

检查您的数据是否为dict类型
如果是，则将字典发送到另一个功能，如下所示
def print_dict(d):
return ",".join([key+":"+str(d[key]) for key in d])

你可以这样做，假设class Car {
private String name;
private int cylinder;
private boolean engine;
private int wheels;
public Car(String name, int cylinder) {
this.name = name;
this.cylinder = cylinder;
this.engine = true;
this.wheels = 4;
}
public Car() {
}
public String startEngine(int fuel){
if(fuel>0){
return "Start button pressed";
} else{
return "First fill some fuel";
}
}
public String accelerate(int speed){
return "Car is accelerated with speed " + speed;
}
public String brake(int speed){
return "Brake is presses. Now speed is " + speed;
}
public String getName() {
return name;
}
public int getCylinder() {
return cylinder;
}
}
class Fortuner extends Car{
public Fortuner() {
super("Fortuner", 4);
}
@Override
public String accelerate(int speed) {
return "Fortuner is accelerated with speed " +speed;
}
@Override
public String brake(int speed) {
return "Now your Fortuner is moving with " + speed + " kph";
}
}
class Hondacity extends Car{
public Hondacity() {
super("Hinda City", 6);
}
@Override
public String accelerate(int speed) {
return "Honda City is accelerated with speed " +speed;
}
@Override
public String brake(int speed) {
return "Now your Honda City is moving with " + speed + " kph";
}
}
class Omni extends Car{
public Omni() {
super("Omni", 1);
}
@Override
public String accelerate(int speed) {
return "Omni is accelerated with speed " +speed;
}
@Override
public String brake(int speed) {
return "Now your Omni is moving with " + speed + " kph";
}
}
public class Main {
public static void main(String[] args) {
for(int j=0; j<3; j++){
Car car = null;
switch (j) {
case 0: car = new Fortuner();
break;
case 1: car = new Hondacity();
break;
case 2: car = new Omni();
break;
}
System.out.println(car.accelerate(50));
}
}
}
是一个dict / json。
代码看起来像这样：

正如@chkri建议先检查你的数据是否是dict，如果是，那么你可以试试这个单行解决方案：
dict={'Name':'ABC', 'Details':{u'Status': u'True', u'Remarks': u'No Remark'}}
print({k:v for k,v in dict.items()})
输出：
{'Name': 'ABC', 'Details': {'Remarks': 'No Remark', 'Status': 'True'}}
