Question

我有以下猫鼬模型。我为status设置了一个枚举，但是status仍然接受除枚举之外的任何值。我在这里做错了什么？当我输入ABCDEF作为值时，它仍然保存在mongodb中。

 import { model, Schema } from 'mongoose';
    import Joi from '@hapi/joi';

    import { USER_STATUSES } from 'enums';

    const userSchema = new Schema({
      firstName: {
        type: String,
        minlength: 1,
        maxlength: 20,
        required: true,
        trim: true,
      },
      lastName: {
        type: String,
        minlength: 1,
        maxlength: 20,
        required: true,
        trim: true,
      },
      email: {
        type: String,
        minlength: 5,
        maxlength: 50, 
        required: true,
        trim: true,
        unique: true,
      },
      mobile: {
        type: String,
        minlength: 5,
        maxlength: 50,
        required: true,
        trim: true,
      },
      password: {
        type: String,
        maxlength: 255,
        required: true,
      },
      status: {
        type: String,
        enum: ['Pending', 'Active'],
        default: 'ABCDEF,
      },
      date: {
        type: Date,
        default: Date.now,
      },
    });

    export default model('User', userSchema);

设置默认值并创建一个新文档时，可能一开始就没有验证。您可以尝试做：

module tb_modules();

reg clk, reset, done_in;
reg [2:0] sel_module;
reg[7:0] val;
reg[7:0] red, green, blue;
wire done_out;
wire[7:0] red_o, green_o, blue_o;

Modules tb( clk, reset, sel_module,red, green, blue, // input signlas
done_in, done_out, // output signals for tgb2gray
val, // brightness values
red_o, green_o, blue_o);


`define read_fileName "C:\\Users\\Sarath\\OneDrive\\Desktop\\desktop\\verilog projects\\xilinx projects\\enhance\\Original.bmp"
localparam ARRAY_LEN = 500*1024;

reg[7:0] data[0: ARRAY_LEN];
integer size, start_pos, width, height, bitcount;



task readBMP;
integer fileID;
// integer i;
begin
fileID = $fopen(`read_fileName, "rb");
$display("%d", fileID);
if(fileID == 0) begin
$display("Error: Please check file path");
$finish;
end else begin
$fread(data, fileID);
$fclose(fileID);

size = {data[5],data[4],data[3],data[2]};
$display("size - %d", size);
start_pos = {data[13],data[12],data[11],data[10]};
$display("startpos : %d", start_pos);
width = {data[21],data[20],data[19],data[18]};
height = {data[25],data[24],data[23],data[22]};
$display("width - %d; height - %d",width, height );

bitcount = {data[29],data[28]};

if(bitcount != 24) begin
$display("Error: Please check the image file. It may be corrupted");
end

if(width%4)begin
$display("width is not suitable");
$finish;
end
// for(i = start_pos; i<size;i = i+1)begin
// $display("%h", data[i]);
// end
end
end
endtask
// Image read complete

integer i, j;
localparam RESULT_ARRAY_LEN = 5000*1024;

reg[7:0] result[0:RESULT_ARRAY_LEN - 1];

always @(posedge clk) begin
if(sel_module == 2'b00)begin
if(reset) begin
j <= 8'd0;
end else begin
if(done_out) begin
result[j] <= blue_o;
result[j+1] <= green_o;
result[j+2] <= red_o;
j <= j+3;
//$display("%d, %d", gray, result[j]);
end
end
end else begin
if(reset) begin
j <= 8'd0;
end else begin
if(done_out) begin
//$display("done_out, %d", done_out);
//$display("something");
result[j] <= blue_o;
result[j+1] <= green_o;
result[j+2] <= red_o;
j <= j+3;
// $display("j-%d", j);
// $display("blue-%d;green-%d;red-%d;", result[j],result[j+1],result[j+2]);
end
end
end
end


//Image Write Start

`define write_filename "C:\\Users\\Sarath\\OneDrive\\Desktop\\result.bmp"

task writeBMP;
integer fileID, k;
begin
fileID = $fopen(`write_filename, "wb");

for(k = 0; k < start_pos; k = k+1)begin
$fwrite(fileID, "%c", data[k]);
end

for(k = start_pos; k<size; k = k+1)begin
$fwrite(fileID, "%c", result[k - start_pos]);
end

$fclose(fileID);
$display("Result.bmp is generated \n");
end
endtask

//Image Write ends

always begin
#5 clk = ~clk;
end

initial begin
clk = 1;
reset = 1;
done_in = 0;
sel_module = 3'b111;
val = 50;

red = 8'd0;
green = 8'd0;
blue = 8'd0;

readBMP;

#10;
reset = 0;

for(i = start_pos; i < size; i = i+3)begin
red = data[i+2];
green = data[i+1];
blue = data[i];

#10;
done_in = 1;
end

#10;
done_in = 1'b0;

#10;
writeBMP;


#10;
$stop;

end

endmodule

猫鼬属性接受除枚举以外的其他值
