カスタムDjango管理アクションが不正なリテラルエラーを返す

Question

私はdjangoモデルCustomerを持っています。モデル管理フィールドの1つを更新するカスタム管理アクションを作成しました。

def age(ModelAdmin, request, queryset): 
if customer.Age == '60 +': 
    customer.Age = 0 
elif customer.Age == '36 - 59': 
    customer.Age = 1 
else: 
    customer.Age = 2 
return customer.Age 

def education(ModelAdmin, request, queryset): 
    if customer.Education == 'Highschool and below': 
     customer.Education = 0 
    else: 
     customer.Education = 1 
    return customer.Education 

def employment(ModelAdmin, request, queryset): 
    if customer.Employment == 'Student': 
     customer.Employment = 0 
    elif customer.Employment == 'Contract': 
     customer.Employment = 1 
    else: 
     customer.Employment = 2 
    return customer.Employment 

def stability(ModelAdmin, request, queryset): 
    if customer.Employer_Stability == 'Unstable': 
     customer.Employer_Stability = 0 
    else: 
     customer.Employer_Stability = 1 
    return customer.Employer_Stability 

def residential(ModelAdmin, request, queryset): 
    if customer.Residential_Status == 'Rented': 
     customer.Residential_Status = 0 
    else: 
     customer.Residential_Status = 1 
    return customer.Residential_Status 

def salary(ModelAdmin, request, queryset): 
    if customer.Salary <= 1000: 
     customer.Salary = 0 
    elif 1000 < customer.Salary <= 10001: 
     customer.Salary = 1 
    else: 
     customer.Salary = 2 
    return customer.Salary 

def loyalty(ModelAdmin, request, queryset): 
    if customer.Customer_Loyalty <= 2: 
     customer.Customer_Loyalty = 0 
    else: 
     customer.Customer_Loyalty = 1 
    return customer.Customer_Loyalty 

def balance(ModelAdmin, request, queryset): 
    if customer.Balance <= 2500: 
     customer.Balance = 0 
    elif 2500 < customer.Balance <= 10001: 
     customer.Balance = 1 
    else: 
     customer.Balance = 2 
    return customer.Balance 

def feat_list(age, education, employment, stability, residential, salary, 
     loyalty, balance): 
    total = age() + education() + employment() + stability() + residential() 
     + salary() + loyalty() + balance() 
    return total 

def allocate_service(ModelAdmin, request, queryset): 
    platinum_customers = [] 
    silver_customers = [] 
    gold_customers = [] 
    message = '' 

    for customer in queryset: 
     if feat_list() <= 11: 
      customer.Service_Level = Service.objects.get(service_name = 
       'Silver Package') 
      silver_customers.append(customer.Name) 
     elif feat_list() > 11 and feat_list() <= 15: 

      customer.Service_Level = Service.objects.get(service_name = 
       'Gold Package') 
      gold_customers.append(customer.Name) 
     else: 
      customer.Service_Level = Service.objects.get(service_name = 
       'Platinum Package') 
      platinum_customers.append(customer.Name) 
     customer.save() 

     if platinum_customers: 
      message = 'The following customers are now Platinum Customers: 
       {}'.format(', '.join(platinum_customers)) 
     if silver_customers: 
      message = 'The following customers are now Silver Customers: 
       {}'.format(', '.join(silver_customers)) 
     if gold_customers: 
      message = 'The following customers are now Gold Customers: 
       {}'.format(', '.join(gold_customers)) 
     if not platinum_customers and not silver_customers and not 
      gold_customers: 
      message = 'No customer changes made!' 
     ModelAdmin.message_user(request, message, level=SUCCESS) 
allocate_service.short_description = 'Allocate Service' 

を次のようにCustomerAdminは次のとおりです：

@admin.register(models.Customer) 
class CustomerAdmin(admin.ModelAdmin): 
    icon = '<i class="material-icons">account_box</i>' 
    list_display = ('Customer_ID', 'Name', 'Gender', 'Nationality', 
     'Account_Type', 'Salary', 'Balance', 'Service_Level') 
    list_per_page = 20 
    list_filter = ('Nationality', 'Gender') 
    actions = [allocate_service] 

ここでの問題は、私はこのエラーを取得していますアクションを実行しようとすることです：

次のように私は関数を作成したアクションを作成するには

ValueError: invalid literal for int() with base 10: '4941" class="action-select'

整数を文字列と混合し、モデル値を上書きします。

elif customer.Age == '36 - 59': 
    customer.Age = 1 

あなたのモデルは、文字列'36 - 59'と整数1を表すことができません。

代わりにあなたが例えば、自分の変数として、これらの値を追跡する必要があります。

def education(ModelAdmin, request, queryset): 
    education = 0 
    if customer.Education == 'Highschool and below': 
     education = 0 
    else: 
     education = 1 
    return education 

データベース・スキーマを変更する機能を持っている場合、これは、最後に

def education(ModelAdmin, request, queryset): 
    if customer.Education == 'Highschool and below': 
     return 0 
    else: 
     return 1 

に短縮することができますこれらの値を格納するために文字列の代わりにchoice fieldsを使用することを検討してください。
