Deleting Entities

Note further modified to delete entities Delete (EntityDto input), can first query, you can also delete the entity directly delete an entity to be converted to pay attention to the type of the primary key

public async Task Delete(EntityDto input)
{
    //先查询再修改
    //var demoObject = await _demoObjectRepository.GetAsync(input.Id);
    //await _demoObjectRepository.DeleteAsync(demoObject);

    //直接删除实体，注意转换id，不转换则删不了
    await _demoObjectRepository.DeleteAsync((int)input.Id);
}

Queries entity

When paging query data sets, you need to sort remapping, Entity Framework 3.1 may be the problem, it could be a problem System.Linq.Dynamic.Core assembly, if the first mapping reordering pages, an error occurs: the specific reasons I have not found another point CountAsync need to reference using Abp.Linq.Extensions; OrderBy need to reference the dynamic query using System.Linq.Dynamic.Core;

Query entity reported errors:

Here is the code (first sort remapped) modified:

public async Task<PagedResultDto<GetDemoObjectForViewDto>> GetAll(GetAllDemoObjectInput input)
{
    //注意这里要用Abp.Linq.Extensions，否则返回的是IEnumerable类型
    var filter = _demoObjectRepository.GetAll()
        .WhereIf(!string.IsNullOrWhiteSpace(input.Filter), e => e.Name.Contains(input.Filter))
        .WhereIf(!string.IsNullOrWhiteSpace(input.NameFilter), e => e.Name.Equals(input.NameFilter));

    //先排序，再映射
    filter = filter.OrderBy(input.Sorting ?? "id asc");//OrderBy来自System.Linq.Dynamic.Core

    var query = (from o in filter
                    orderby o.Id
                    select new GetDemoObjectForViewDto()
                    {
                        DemoObject = ObjectMapper.Map<DemoObjectDto>(o)
                    });

    var totalCount = await query.CountAsync(); //CountAsync来自Abp.Linq.Extensions

    var demoObject = await query
        .PageBy(input)
        .ToListAsync();


    var result = new PagedResultDto<GetDemoObjectForViewDto>()
    {
        TotalCount = totalCount,
        Items = demoObject
    };
    return result;

Deleting Entities

When you delete an entity, not by post, prompts 405 errors, have not found the reason may be that you need to pass http header parameters, here only use the delete method, you can delete entities:
