如果有 DataContext，则该方法不会启动

Question

美好的一天

我正在尝试硬删除软删除的记录，我有一个方法Task PermanantlyDeleteDeal(GetDealInput input)当我调用该方法时它不会进入。

由于样板文件 0.9.6 不是硬删除，我现在使用 Database>DataContext.cs class 执行硬删除

这是我的 DataContext class

public class DataContext : DbContext
{
    public virtual DbSet<Deal> Deal{ get; set; }   

    public DataContext()
       : base("Default")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
    }}

这是 javaScript 上你调用方法

的函数

function DeleteLead(btnCaller) {
abp.message.confirm('Lead will be deleted.', 'Are you sure?', function (isConfirmed) {
    if (isConfirmed) {
        var button = $(btnCaller);
        var proposalId = button.data('content');
        var proposalObject = Object({
            Id: proposalId
        });
        abp.ui.setBusy();
        _leadService.permanantlyDeleteLead(proposalObject).done(function (result) {
            abp.notify.success('Successfully deleted a proposal', 'Quotation deleted');
            Refresh();
        }).always(function () {
            abp.ui.clearBusy();
        });
    }
});

}

这是 PermanantlyDeleteComment

public async Task PermanantlyDeleteDeal(GetDealInput input)
    {
        UserFriendlyException ufex = null;
        try
        {
            DataContext db = new DataContext();

            using (Repository.Repository<Deal> repo = new Repository.Repository<Deal>(db))
            {
                using (Repository.Repository<DealComment> dealCommentRepo = new Repository.Repository<DealComment>(db))
                {
                    using (Repository.Repository<Proposal> proposalRepo = new Repository.Repository<Proposal>(db))
                    {
                        using (Repository.Repository<Quotation> quotationRepo = new Repository.Repository<Quotation>(db))
                        {
                            Deal deal = repo.GetById(input.Id);
                            List<DealComment> listOfDealComments = dealCommentRepo.GetAll().Where(dc => dc.DealId == deal.Id).ToList();

                            List<Proposal> listOfProposals = proposalRepo.GetAll().Where(x => x.DealId == deal.Id).ToList();
                            List<Quotation> listOfQuotations = quotationRepo.GetAll().Where(x => x.DealId == deal.Id).ToList();

                            if (listOfProposals.Count > 0 || listOfQuotations.Count > 0)
                            {
                                string message = string.Empty;

                                message += listOfProposals.Count > 0 ? "Cannot delete deal, this deal is linked to:\nProposals\n" : "Cannot delete deal, this deal is linked to:\n";

                                foreach (var item in listOfProposals)
                                {

                                }

                                message += listOfQuotations.Count > 0 ? "Quotations:\n" : "";

                                foreach (var item in listOfQuotations)
                                {
                                    message += $"- {item.Description}\n";
                                }

                                ufex =  new UserFriendlyException("Ooops! There is a problem.", $"{message}");

                                throw ufex;
                            }
                            else

                                foreach (var item in listOfDealComments)
                                {
                                    dealCommentRepo.Delete(item);

                                }

我过去遇到过同样的问题，要解决这个问题，我必须确保项目引用的 entity framework 的版本与 entity framework 对于解决方案中的所有项目。

如果在 DataContext class 中需要，请确保启用

modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

关键是要与 ABP 上下文生成的名称相同。

如果有 DataContext，则该方法不会启动

The method is not kicking in if there is DataContext
